== Description ==

The '''{{Specs|name}}''' (shortened to '''{{Specs|pseudonym}}''') is a rank {{Specs|rank}} American medium tank {{Battle-rating}}. It was introduced in [[Update 1.87 "Locked On"]].

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}

The M1A1 is essentially an [[IPM1]] armed with a 120 mm M256 gun, meaning the armour is almost identical to its tech-tree predecessor. The tank features composite armour in gun mantlet, turret cheeks, sides and lower front plate, with composite side skirts affording some protection along the frontal half of the vehicle's hull. The M1A1 retains the Abrams series' exceptional protection against chemical energy projectiles, with the turret cheeks affording some 1,200 mm RHAe against shaped charges and the hull providing around 600 mm. However, the kinetic energy protection of the tank is quite lacklustre compared to its top tier compatriots, especially against the best rounds fielded by other nations' main battle tanks; all of which can easily penetrate the Abrams frontally in practically any location. This makes the tank quite vulnerable to enemy fire. However, the M1A1 also retains the excellent survivability of the Abrams series, with a spread out crew, separate ammunition compartment and shielding for fuel tanks and the engine compartment that make the tank unlikely to die in a single shot. However, don't expect to be able to fire back if you get penetrated: most penetrating hits will knock out at least one of these components/crew members: gun breech/barrel, turret traverse/elevation, gunner or loader, track(s), engine.

=== Mobility ===
{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=2,058|rbMinHp=1,343}}

The {{PAGENAME}} features the same 1,500 horsepower AGT-1500 gas turbine equipped on the other Abrams tank, though the tank has gotten several tons heavier. When stock, the vehicle accelerates quite sluggishly and features a horrendously slow hull traverse. Fully upgraded however, the {{PAGENAME}} is quite nimble with decent power-to-weight ratio and traverse capability. At 68 km/h of top speed and 40 km/h in reverse, the tank is comparable to its counterparts.

{{main|M256 (120 mm)}}

The M1A1's gun handles very well, with a very efficient stabiliser that allows accurate fire at any speed and a very fast 40 degrees per second turret traverse. The gun has good depression and elevation angles. An aced crew can reload the gun in just six seconds, which is comparable to the Leopard 2A5, Leclerc and T-80U, although slower than the Type 90 and Challenger 2. The penetration of the M829 APFSDS, even though is comparable if not a little better that its contemporaries, is not enough to handle most of the soviet MBTs it is going to face.

== Usage in battles ==


'''Stock Gameplay:'''

As with any vehicle, the M1A1 finds itself at a serious disadvantage while stock. Without access to thermal imaging or the M829 or M829a1 APFSDS round, users will need to play more carefully. While the M830 HEATFS round is powerful, it struggles against composite armour and ERA, as well as having lacklustre post-penetration effects. Generally stock M1A1 tank commanders should avoid areas with lots of foliage, as here the lack of thermals will be especially detrimental. Additionally players will have to aim more carefully to deal effective damage with the M830 HEAT round.

'''Spaded Gameplay:'''

The M1A1 is a 10.7 glass cannon without the cannon part most of the time. The M829a1 APFSDS round has plenty of penetration against non soviet opponents and also non soviet tanks,A shot to the LFP should be adequate to kill most tanks . The gun, ammo, and reload rate are comparable to other 10.7 vehicles.. The turret protection on the M1A1 is not capable of stopping any of the best APFSDS rounds at its tier. Rounds like 3BM42 Mango are able to penetrate at ranges up to 3,500 m. With this in mind, players should not rely on their armour.

'''Close Range Engagements:'''

The M1A1 is not a brawler. It has impressive acceleration and gun handling, giving it an edge over other vehicles, but anytime it faces the soviets, most times the rounds will not pen provided if shot at the ufp or turret cheeks. The hull armour gives the M1A1 a fighting chance against HEAT rounds,even though most times it will hit the UGP and bounce right into the player's turret ring, knocking out the cannon breech, the gunner or the turret traverse. It is suggested to use its speed to get to a vantage position or a choke point and eliminate any target that gets through there.

'''Long Range Engagements:'''

The M1A1 is capable at long range, but is outclassed very few tanks at the br. The cannon is powerful, but not especially so compared to German counterparts. The biggest issues the M1A1 will face in regards to long range engagements are the turret armour and lack of commanders thermals. While the M829a1 APFSDS round will fail to penetrate the turret cheeks of vehicles like T80U and Leopard 2A5, their rounds will have no such trouble with the M1A1. The lack of commanders thermals makes it difficult to scout for enemies while in full hull down, although players can bind a button to switch to the machine gun as their main weapon. This will allow them to see through the machine gun sight with a thermal imager, giving them an elevated vantage point through the thermals.

'''Gameplay summary:'''

Although the M1A1 is somewhat weak when stock, it is an adequate frontline tank while spaded. The powerful round and gun give it a strong position in the U.S. top tier lineup. However M1A1 tank commanders should remember that their turret cheeks can be penetrated by some rounds. This means it does best in close to medium range fights.

=== Pros and cons ===


'''Pros:'''

* Turret exceptionally well protected against chemical rounds
* Decent mobility when upgraded
* Ammunition in the turret, when detonated, generally will not spread to the crew compartment
* The fuel tanks and engine compartment are separated from the crew compartment by steel plates, increasing the time it takes for a fire to destroy the vehicle
* Reload speed of the 120 mm is decent; 6 seconds with an aced crew level
* Powerful M829A1 APFSDS round that makes easy work of the enemy tank

'''Cons:'''

* Stock vehicle is sluggish
* Stock rounds are quite inadequate against many of the main battle tanks the vehicle faces
* Ammunition variety is limited to three choices, a HEAT-FS and 2 APFSDS round
* Reload time slower than 105 mm armed predecessors
* Hull and turret armour less effective against kinetic rounds, plus are lacking in protection against the armaments of current Rank VII vehicles
* Lacks the M830A1 proximity-fused HEATFS round that the M1A1HC and M1A1 AIM has at the same BR
* Weak turret ring armour and upper hull plate ricochets will often/sometimes lead to fatal shot traps and ammo racks.
* Like with most Abrams series tanks, the engine deck is slightly raised, meaning that you will not be able to depress the gun over the rear of the tank.

== History ==

Almost as soon as the first production M1 Abrams MBTs began rolling off the assembly line, did American engineers begin working on an up-gunned version of the Abrams. They succeeded in this endeavour in 1981, after a prototype Abrams, designated M1E1, was successfully fitted with a 120mm Rheinmetall smoothbore cannon.
[[File:M1A1 M2 Browning - National Archives 6458905.jpeg|x250px|right|none|thumb|An M1A1 Abrams at Fort Knox.]]

Showing promising performance, work on the vehicle continued. At the same time, an upgraded version of the original Abrams, the IPM1, which featured improved protection and a larger turret was briefly produced between 1984 - 1986. The resulting M1A1 Abrams inherited the upgrades from the IPM1 and combined them with the M256 120 mm smoothbore cannon, a licence-built version of the German original.

The M1A1 was adopted for service in 1984 and was produced alongside the IPM1 for a short while since 1985 until the older modification was phased out of production.

The M1A1 saw its first use during the U.S. deployment in the Gulf War in 1991. Faced against arguably inferior Soviet-era tanks, the M1A1 had successfully proven its worth in tank-on-tank engagements but exposed new problems concerning its performance and vulnerability in urban environments. This led to further upgrades for the vehicle being developed later on.

Production of the M1A1 seized in 1992, with over 5,800 units being produced, including Egyptian and Australian export models. The original M1A1 chassis still serves today, albeit as upgraded variants which have undergone several modernization efforts.

'''Notes:''' 


=== Mobility ===
{{Specs-Tank-Mobility}}

The LAV-AD's mobility is rather superb. As a wheeled vehicle, it has good speed on roads. Despite being similar in appearance and having a weaker engine than the [[M1128]], the LAV-AD accelerates much faster due to its lighter weight, resulting in a higher power-to-weight ratio, and it also has a slightly faster reverse speed. The engine is also relatively quiet, allowing for stealthy movements and ambushes.

{{Specs-Tank-Weapon|4}}

{{main|GAU-12U (25 mm)}}

The main armament of the LAV-AD is the 25 mm GAU-12U rotary autocannon. It functions similarly to the 20 mm [[M168 (20 mm)|M168]] Vulcan found on the [[M163]] earlier on in the tech tree, but with a reduced ammo capacity of only 1,000 rounds total (500 ready, 500 reserve instead of 1,100 ready, 1,100 reserve) and fire rate (1,800 rpm instead of 3,000 rpm) due to the limited room in the vehicle and larger calibre ammunition. The gun is also fully stabilized, with handling akin to that of the [[HSTV-L]]; slower than the [[M163]] and [[M247]] Sergeant York but still fast enough to react to most aerial targets at close range, particularly helicopters and slow, low-flying jets. Like most other AAs, it comes with a Default, AP, and HE belt. The Default belt has a 1:1 AP to HE ratio and is the only belt the vehicle has access to when stock. The HE belt has a 3:1 HE to AP ratio while the AP belt has a 3:1 AP to HE ratio. The former is more effective against aircraft while the latter is more effective against armoured vehicles. The AP round is the same across all belts, and can penetrate 91 mm of armour at point blank range. Combined with the relatively high fire rate, it can easily destroy barrels, tracks, and machine guns with ease as well as being able to shred light vehicles.

{{main|Hydra 70}}

The LAV-AD also has access to Hydra 70 M247 rockets with a researchable modification. This modification gives the vehicle an additional weapon set-up, replacing the Stinger pod above the main gun with a Hydra 70 rocket pod with 19 rockets, similar to those found on [[AH-1 (Family)|AH-1 Cobras]] and [[AH-64 (Family)|AH-64 Apaches]]. The Hydras are fired as a secondary weapon.

The LAV-AD also comes with [[FIM-92 Stinger]] missiles. The missiles are IR guided, meaning they require a lock-on before firing. The vehicle has FIM-92Es by default and can unlock FIM-92Ks as a later modification. These are the same Stinger missiles used by the [[Ozelot]] in the German tech tree and function the same way. The missiles are launched as special weapons.

== Usage in battles ==
when used in battles: the player can either aa or as anti tank,using the lav fast speed , the player can easily find themselves deep into enemy territory where enemys are more relaxed compared to near the mid points of the map,the player can use this advantage by either hiding and waiting for planes to be distracted on friendly tanks and shooting them down or used to attack unsuspecting spaa and ifvs/light tanks from mid range and then closing up close to killing mbts,having the rocket pod unlocked makes quick work of enemy armor if you can get on their flanks additionally the lav can be used a very good bait against the enemy to lure their concentration while you teammates may shoot the said tank.

'''<big>Against Aircraft:</big>'''

The lav's stingers are decent but anyone with a brain can notice the smoke trail and evade, leading to the use of 2-3 stingers to get a hit

while the gun has fast firerate,it has terrible drop meaning it is a bit more hard to hit but you have a lead indicator upon locking on the aircraft

the best option is to lure the plane into thinking it is safe and engage it with the 25mm upon entering 3km to minimize the chance of survival and launch a stinger at the plane if you did not fully kill it with the 25mm

'''<big>Against Tanks:</big>'''

The lav is mobile ,outpacing most light tanks at the br it can use this to its advantage by reaching the enemys territory and flanking spaas and light tanks

However, against mbts the lavs 25mm can deal with most mbts due to lack of side armor but the after damage is very weak,against russian armor the lavs struggles to pen the side armor ,in such cases bringing the 70mm hydra pod the lav is a good choice making the vehicle good against any mbts and with solid aim can kill most mbts with 2 heat grenades(the 70mm hydra) combine this with the mobility makes the lav a beast if given a solid flank

'''<big>Threats:</big>'''

In the lav anything above 12.7mm poses a big threat to the user in such cases the player is recommended to kill the vehicle with auto cannons first as they can shred the lav, big caliber tank shells can overpenetration the tank and do minimal damage and they will take time to reload after that

=== Pros and cons ===


'''Pros:'''

* Has access to Hydra 70 rockets
* The 25 mm GAU-12U cannon shreds any air vehicles in its range
* The 25mm GAU-12U has no tracers making enemy planes/tanks harder to notice your location when firing
* Highly mobile thanks to its light weight and is also amphibious
* Can carry up to 16 SAMs if you choose to not have Hydras
* Has access to 2nd generation thermal sights for the gunner
* Has optical tracking meaning air targets will not receive RWR pings when locked onto
* Comes with smoke grenades stock
* Laser rangefinder automatically adjusts the sights
* Not equipping Hydras enables the Stingers to be fired in relatively quick succession with no reload
* Can fire Stingers while on the move

'''Cons:'''

* The SAM has only a maximum overload of 10G which may prove difficult against planes with high manoeuvrability
* Long reload for the 25 mm gun
* Bringing the Hydra rocket pod reduces the number of available Stingers and gives them a lengthy reload time after 4 have been launched
* Penetrable by heavy machine gun fire and is prone to overpressure damage
* Shorter missile range and lacks a search radar when compared to its contemporaries like the [[Roland 1]], [[FlaRakPz 1]], and [[XM975]] at the same BR
* MAW detects missile launches and Stingers are prone to being diverted by flares
* No proximity-fused ammunition
* Hydra rockets are hard to aim due to their low velocity and do not work properly with the laser rangefinder
* Low sight FOV and relatively high zoom levels makes it hard to use against multiple targets up close
* 25 mm gun is inaccurate at longer ranges

== History ==

=== [[wt:en/news/7598-development-lav-ad-revolving-firepower-en|Devblog]] ===

Development of the LAV-AD began in 1987 after a contract was signed with both the FMC Corporation and General Electric to design a SPAA variant for the LAV-25 for the USMC. Both companies began developing a system based on the USMC requirements that it had to be armed with a 25 mm cannon and possess provisions for mounting Stinger missiles and Hydra-70 rockets. While the FMC company opted to outfit their design with the same M242 cannon used on the base model of the LAV-25, General Electric decided to go for the GAU-12 'Equalizer' Gatling style rotary cannon.

Having reviewed both prototypes, the USMC decided to procure General Electric's design, placing an initial order for 125 vehicles to be produced. By 1996, the LAV-AD had formally been adopted into service. Despite the initial plans to produce over 100 vehicles, only 17 were actually manufactured due to funding issues. In 1998, the final unit was delivered to the USMC and further development of the vehicle was discontinued due to high maintenance costs. Among other operations, the LAV-AD was used in combat action in Iraq.

ADATS

2022-09-16T14:56:56Z

U67347324: /* Pros and cons */

{{Specs-Card
|code=us_adats_bradley
|images={{Specs-Card-Image|GarageImage_{{PAGENAME}}.jpg|ArtImage_{{PAGENAME}}.png}}
}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} American tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.89 "Imperial Navy"]].

The ADATS is essentially an [[M3 Bradley]] with a heavily modified turret. The crew was moved away from the turret and controls it via interface in the back of the tank. The turret is fully automatic and now carries two enormous missile racks, a radar and the same old gun is tweaked to fire three times faster.

While designations for this tank go all over the place, the ADATS can be simply called a multi-purpose tank, as it can fight fast jets and heavier tanks alike with missiles, while dealing with lightly armoured tanks and slower aircraft by using a gun and/or missiles.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}


'''Armour type:'''

* Aluminium alloy 5083 (Hull front, turret)
* Aluminium alloy 7039 (Hull sides, rear, optics)
* Rolled homogeneous armour (Hull plates)

{| class="wikitable"
|-
! Armour !! Front (Slope angle) !! Sides !! Rear !! Roof
|-
| Hull || 25.4 mm + 6.35 mm (39-60°) ''Upper glacis'' 25.4 mm (7-39°) ''Lower glacis'' || 25.4 mm + 6-6.35 mm || 25.4 mm + 6.35 mm || 25.4 mm
|-
| Turret || 12.7 mm ''Turret front'' 25.4 mm ''Gun mantlet'' 19 mm ''Optics housing'' || 12.7 mm || 6.35-12.7 mm || 12.7 mm
|-
|}

'''Notes:'''

* Suspension wheels are 10 mm thick
* Tracks are 15 mm thick

The ADATS boasts the same protection as the regular [[M3 Bradley]] hull-wise, with one key difference being that the side armour is thinner by 19 mm. High-calibre machine guns such as the 20 mm on French MBTs will easily penetrate the sides and at times even the front part of the hull. It's not advisable to use the ADATS as a front-line vehicle but rather as a second-line support vehicle by setting up in key-points around maps.

[[File:Bradley ADATS Side-view.jpg|thumb|300x300px|The gap between the Loader/Gunner and the Driver visualized with a green square. Also, you can see the unmanned turret.]]
One upside for the ADATS is that the turret is completely unmanned, meaning that any Armour-piercing shells will over-penetrate with no injuries to the crew at all (be aware that explosive shells can cause the rockets to explode and instantly destroy the vehicle). The three crew members are situated in the hull with a massive empty space between the loader/gunner and the driver when approached from the side. Every enemy you face will most likely over-penetrate that section and do minimal damage to the vehicle itself.

Overall, the ADATS can be quite a 'meme' vehicle as it can sometimes sustain 5-7 direct hits even centre-hull, seeing as most rounds just pierce and exit the armour without generating shrapnel, over-penetrating and forcing enemies to snipe for crew members.

{{Specs-Tank-Weapon|2}}

{{main|M242 (25 mm)}}

The main armament of the ADATS is the M242 25 mm automatic cannon, the same as found on the M3 Bradley, but enjoys a faster rate of fire (500 rounds per minute, compared to the Bradley's 201 rounds per minute). When stock, like most AA vehicles, it starts with a belt of equal parts armour-piercing and high-explosive, though it is worth mentioning the AP rounds are sabot rounds with 101 mm of penetration at 100 m against flat armour. This allows it to easily and effectively take on both air and ground threats simultaneously without needing to worry about ammunition costs. However, should you wish to use this vehicle in a dedicated anti-aircraft role, you can unlock a belt with three parts HE to one AP in Tier I modifications. This must be unlocked in order to unlock M791, the AP belt. With this belt, dealing with any and all lightly armoured vehicles and even quite a few of the MBTs is possible from the side. In regards to how much you should take, you may as well take a full ammunition load. At any range, this vehicle can and will be penetrated by any vehicle that looks in its general direction, so it's not like your armour is going to stop you from being ammo-racked by fin-stabilized sabot anyway. Also, due to the cannon's rather high rate of fire and ammunition count of 600 rounds, it's worth taking as much as you can carry.

=== Additional armament ===
{{Specs-Tank-Weapon|1}}

{{main|MIM146}}

Secondary armament of the ADATS (or primary, depending on how you choose to play it) are the MIM146 dual purpose guided missiles. You can effectively use these against any target you can point them at, due to the facts that they air-burst near aircraft, usually one-hit killing them with the 7.86 kg of TNT equivalent, and have 900 mm of penetration against armoured targets. With a velocity of 1,027 m/s, aiming these things and tracking moving targets isn't an issue whatsoever. You point, you click, and the target usually dies in a single hit. In the event that, by some miracle of God himself, the target persists in clinging to their life, you can fire the MIM146 as fast as you'd like to, meaning follow-up shots are quick and easy, and with the aforementioned 900 mm of penetration, anything you shoot these at WILL be penetrated, unless the angle of impact is extreme.

== Usage in battles ==

'''Stock Gameplay:'''

As with any vehicle, the ADATS finds itself at a disadvantage while stock. Without access to the thermal vision devices, players will need to be more alert in order to spot enemies. While other modifications like artillery or smoke grenades can be helpful, the lack of thermals is a much larger issue. However the ADATS is relatively well off stock compared to most high tier vehicles, as the stock 25 mm belts include APDS rounds, and the radar is capable of spotting air targets for you.

'''Spaded Gameplay:'''

The ADATS is an excellent multi-purpose support vehicle when spaded. Being able to target both enemy tanks and enemy aircraft, it can be a great tool for the team. However, there are some limitations to the vehicle, namely the low missile count and lack of armour. While survivability is decent due to the empty turret, the armour is very thin and the missiles can sometimes explode when hit. This means that the ADATS does best sitting behind friendly tanks, in a support role. Additionally the missiles can run out quickly, as there are only 8 to engage both air and ground targets. ADATS players should try and conserve their missiles, as they are very valuable.

'''Close Range Engagements:'''

The ADATS is capable at close range, but it will die very easily to enemy fire. The 25 mm bushmaster autocannon can penetrate the side armour of most enemy tanks, but it will not disable the enemy as quickly as their large cannons are capable of killing the ADATS. The ADATS missiles can be useful at close range as well.

'''Long Range Engagements:'''

The ADATS is more capable at long range, where it can rely on thermal vision and the very fast ADATS missiles to disable enemy targets. The only issue at long range is the low amount of missiles, so shots should be taken with care. Additionally, the ADATS can be quickly disabled if the hull is exposed, so staying hull down is advised. The radar should also be turned off and on as needed, as it provides a good indicator of where you are for enemy ground vehicles, but is very useful in spotting air targets.

'''Gameplay summary:'''

The ADATS is an excellent support vehicle, able to defend teammates from both enemy air and ground threats. The ADATS missiles are excellent at disabling any target, although the low ammo count should be considered. The ADATS is also capable of locking an enemy aircraft without alerting their RWR, by turning off the radar. One must take excellent care in their method of positioning.

=== Pros and cons ===


'''Pros:'''

* Has access to 8 x multi-purpose missiles, can effectively eliminate both aircraft and tanks
* tank has similar playstyle of the m3bradley if chose to be used against tanks
* Missiles can penetrate up to 900 mm of armour and can cause overpressure with 7.9 kg TNT equivalent
* Missiles are very fast with a speed of 1,027 m/s
* Powerful 25 mm cannon with good APDS for ground targets and HE ammunition for use against air targets
** Can fire 131 rounds before overheating
* Gunner operates the turret and weapons from behind protective hull instead of being in the turret itself
* Built on the chassis of M3 Bradley- good mobility and acceptable armour
* Modifications are researched fairly quickly
* Effective radar with good range
* Can lock on to aircraft with the radar disabled as the ADATS tracks using an electro-optical targeting system, making sneak attacks easy
* Missiles can even be fired without lock on and retain their proximity fuse against aircraft

'''Cons:'''

* Thin armour is not effective against larger cannons
* High profile makes it hard to conceal, it is easily spotted
* Can be destroyed if directly rammed by a plane
* The three crew members are all situated within the hull, and can all be rendered unconscious if a shot penetrates the hull
* The 25 mm autocannon can't reliably penetrate MBTs frontally
* The missiles are essentially giant exposed ammo-racks
* Lack of stabilizer makes firing on the move difficult and increases the time to aim the weapons when suddenly braking
* Missiles cannot be fired on the move, only guided
* Lacks turret stabilization
* No commander fire control
* Vulnerable to the [[Damage mechanics#Overpressure|overpressure]] mechanic
* ERA defeats the MIM146 ATGM

== History ==

The ADATS was developed at the end of the 1980s as a general-purpose weapon capable of bringing down low-flying airborne targets as well as armoured opponents. Hence the abbreviation: Air Defence Anti-Tank System. The system was comprised of radar for detecting and tracking targets, a complex radio kit for coordinating multiple vehicles, and eight MIM-146 guided missiles in transport and launch containers. The US Army version was built on the Bradley IFV chassis and fitted with a 25 mm autocannon. Notwithstanding the fact that it was selected after a US Army competition for the Forward Area Air-Defence program, it was found to be excessively expensive to manufacture and never made it to serial production on the Bradley chassis.

=== Mobility ===
{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp= 1,065|rbMinHp= 663}}

The {{PAGENAME}}'s turret is installed on the hull of an [[M48A1|M48 medium tank]], because of this they have roughly similar mobility. The {{PAGENAME}} is about 3 tons heavier than the M48A1 (49.3 tons vs. 46.4 tons), and has a slightly weaker engine, which translates into a slightly more sluggish machine compared to the M48A1. The M48A1 has a max engine power of 810 hp, while the {{PAGENAME}}'s engine power is 750 hp. For a vehicle this heavy, it has fairly good mobility. When spaded, it can comfortably hit a top speed of 45 km/h on flat terrain, while in cross-country you will have a top speed of around 25 km/h. While going backwards, the top speed is somewhat less impressive: about -9 km/h.

==== Ammunition ====

* '''Default:''' {{Annotation|HEFI-T*|High-explosive fragmentation incendiary tracer (self-destroying)}}{{-}}{{Annotation|AP-T|Armour-piercing tracer}} - Good general ammunition, a hit on an aircraft typically means its destruction while still enough to do damage to armoured ground vehicles, especially if it shoots into the side of an enemy tank (weaker armour). Good to start with until comfortable with other types of ammunition.

* '''40 mm AP-T:''' {{Annotation|AP-T|Armour-piercing tracer}}{{-}}{{Annotation|AP-T|Armour-piercing tracer}}{{-}}{{Annotation|AP-T|Armour-piercing tracer}}{{-}}{{Annotation|HEFI-T*|High-explosive fragmentation incendiary tracer (self-destroying)}} - Very powerful ammunition which can be used against ground targets with significantly more penetration than other 35-40 mm AP-T projectiles. Will easily destroy any target with side shots even outside the point-blank range and can destroy lighter targets and weak spots from the front even against main battle tanks.

* '''M811:''' {{Annotation|HEFI-T*|High-explosive fragmentation incendiary tracer (self-destroying)}}{{-}}{{Annotation|HEFI-T*|High-explosive fragmentation incendiary tracer (self-destroying)}}{{-}}{{Annotation|HEFI-T*|High-explosive fragmentation incendiary tracer (self-destroying)}}{{-}}{{Annotation|AP-T|Armour-piercing tracer}} - Unlike the M822 HEE-VT shells, these require direct hits on aircraft to do significant damage, but if problems are experienced with M822 detonating too early this belt may be your best choice.

* '''M822:''' {{Annotation|HE-VT*|High-explosive variable time fuze (self-destroying)}}{{-}}{{Annotation|HE-VT*|High-explosive variable time fuze (self-destroying)}}{{-}}{{Annotation|AP-T|Armour-piercing tracer}} - Proximity-fused shells that absolutely obliterate aircraft when they make contact, though if they detonate too early, they will do little to no damage. Somewhat unreliable in if they detonate within range of the target, but when they do the target will quickly take considerable damage if not destroyed. The only ammunition for self-propelled anti-aircraft guns that which can cause enough shrapnel damage to bring down planes and helicopters even with near misses. This round should be the go-to anti-air ammunition, although the M811 is a good backup if the M822 is problematic for the gunner.

'''Notes''':

* With a single ammunition rack, you can bring only 1 type of ammunition in battle.

== Usage in battles ==

The M247 Sgt York is a very deadly SPAA, The M247 is deadly to some lightly armoured vehicles but even deadlier to Aircraft. When using the M247 you can easily shred some lightly armoured vehicles like the Leopard 1. Where the speciality for the M247 is with its Proximity fused 40 mm rounds. They will shred any aircraft within a 2.0 km radius. You can play the vehicle mostly in 2 ways. You can push and try defending caps from the enemies and keeping the skies clear, or stay back behind cover and keep the skies clear for your allies, while using your AP rounds to fend off enemy vehicles.

Generally, enemy tanks should be avoided - especially from the front - but in desperate times or the right circumstances many of them can be dealt with. Due to the decent armour-piercing ammunition used by the M247, most tanks at its BR can be penetrated from the side. Common examples of tanks that are easy to penetrate from the side are the Leopard 1 and OF-40 families. Soviet tanks are quite a bit harder to penetrate and may not be penetrated except when nearly perpendicular to your guns. All light tanks and SPAAs can be penetrated from the side and many of them from the front as well. Again, full sized tanks should not generally be engaged except when there is no other choice, in which case aiming for the gun barrel may be the best choice, except when engaged from the side. Light vehicles, on the other hand, can be engaged favorably in most circumstances.

'''Ammunition'''

The recommended ammunition belt is the M822 belt, which includes both the AP and HE-VT rounds.

This belt is the best at taking out enemy aircraft because the proximity fuze rounds make it so that a direct hit on an aircraft is not needed, the shells must only pass near the aircraft to damage it. This belt also includes armour-piercing rounds so that if a ground target is spotted it can be engaged when necessary. The AP rounds have enough penetration (94 mm maximum) to go through the fronts of many light tanks and SPAA vehicles, as well as the sides of most other vehicles including main battle tanks (MBTs). The only class of vehicles that can not be penetrated in a majority of cases is the heavy tank class, which should be avoided as much as possible.

=== Pros and cons ===


'''Pros:'''

* Has access to 12 smoke grenades
* hull has good protection against most light tank caliber rounds
* Can retract and extend both search and tracking radars to reduce silhouette
* Twin stabilized 40 mm cannons have a high rate of fire
* Large ammunition count ensures that you will have plenty to fire throughout a match
* Potent proximity ammunition for anti-aircraft use
* The HE-VT belt has no tracers making it almost near impossible for enemy planes or helis to see the shells
* 40 mm cannons pose a serious threat to lightly-armoured vehicles, and can penetrate the sides of some tanks
* Radar allows for high range of detection and very accurate tracking, with 10 km tracking and 40 km detection range
* Has access to night vision devices, a laser rangefinder, commander sights, and commander fire control

'''Cons:'''

* Vulnerable to enemy armour, artillery strikes and air attacks
* Only three crew members
* Radar is tall and can expose your position
* While the hull armor is decent the turret armor is only 5mm which is easy to penetrate with any high caliber mgs or 50 cals
* The M247 is sluggish especially when stock, will usually not be able to keep up with MBTs
* The high rate of fire can deplete the ammo quickly without proper trigger discipline
* HE-VT belt is only available at tier IV
* Cannot carry more than one type of ammo belt
* The gunner sight optics only has one zoom setting (12.0x with a sight FOV of 6) meaning that you may struggle to engage tanks and to lock/eliminate aircraft
* 5-minute long restock time on a capture point after depleting ammo
* No IRST mode and cannot lock onto targets when the radar is off
* Using the laser rangefinder does not adjust the range of the guns

== History ==


The M247 "Sergeant York" was designed in the late 1970's as a purpose-built SPAAG. It was designed to fight alongside the [[M1 Abrams]] and [[M3 Bradley|M2/M3 Bradley]], in order to provide cover against aircraft. There were other SPAA vehicles in service at the time; these were the [[M163|M163 Vulcan]] and the MIM-72/M48 Chaparral. The former being a 20 mm rotary cannon mounted on an armoured personnel carrier, and the latter being a heavily modified armoured personnel carrier chassis with a surface-to-air missile launcher. Neither of those two vehicles were designed as SPAA's, and so, did not have the necessary performance to be adequate at their job. The M247 was designed as a replacement for both of the previous vehicles.

Designs from a multitude of companies were entered into the competition. Only two were selected for testing: the Ford XM-247 with twin Bofors 40 mm cannons and the General Dynamics XM-246 with twin Oerlikon 35mm cannons. The two prototypes were tested, and the XM-247 was selected as the winner, although the XM-246 had outscored it in all the shooting tests. The M247, as it was soon designated, ran into many problems. The radar was extremely deficient; it had a hard time distinguishing trees from planes, and if the guns were pointed too high, they would get in the radar's way and confuse it even more. In addition, it took too long for the radar to pick up a target and for the guns to actually take aim. In addition, the turret traverse speed was much too slow, the vehicle it's self was too sluggish to keep up the M1's and M2's, and it was unreliable in cold weather. Eventually, the program was cancelled after more testing, where it was proven the system could not even shoot down stationary drones. There was still a need for an anti-aircraft vehicle that could keep up with modern vehicles, so Oerlikon Canada created the [[ADATS]] anti-aircraft missile system. This was not as successful as hoped, and was only accepted into Canadian service. The void was eventually filled by the M6 Linebacker, an M2 Bradley with Stinger missiles instead of TOW missiles. The Linebacker was capable of keeping up with modern armoured forces, which was the reason for its acceptance, even though the Stingers were not as effective as the ADATS missiles<ref>https://en.wikipedia.org/wiki/M247_Sergeant_York</ref>.

=== Mobility ===
{{Specs-Tank-Mobility}}

The LAV-AD's mobility is rather superb. As a wheeled vehicle, it has good speed on roads. Despite being similar in appearance and having a weaker engine than the [[M1128]], the LAV-AD accelerates much faster due to its lighter weight, resulting in a higher power-to-weight ratio, and it also has a slightly faster reverse speed. The engine is also relatively quiet, allowing for stealthy movements and ambushes.

{{main|GAU-12U (25 mm)}}

The main armament of the LAV-AD is the 25 mm GAU-12U rotary autocannon. It functions similarly to the 20 mm [[M168 (20 mm)|M168]] Vulcan found on the [[M163]] earlier on in the tech tree, but with a reduced ammo capacity of only 1,000 rounds total (500 ready, 500 reserve instead of 1,100 ready, 1,100 reserve) and fire rate (1,800 rpm instead of 3,000 rpm) due to the limited room in the vehicle and larger calibre ammunition. The gun is also fully stabilized, with handling akin to that of the [[HSTV-L]]; slower than the [[M163]] and [[M247]] Sergeant York but still fast enough to react to most aerial targets at close range, particularly helicopters and slow, low-flying jets. Like most other AAs, it comes with a Default, AP, and HE belt. The Default belt has a 1:1 AP to HE ratio and is the only belt the vehicle has access to when stock. The HE belt has a 3:1 HE to AP ratio while the AP belt has a 3:1 AP to HE ratio. The former is more effective against aircraft while the latter is more effective against armoured vehicles. The AP round is the same across all belts, and can penetrate 91 mm of armour at point blank range. Combined with the relatively high fire rate, it can easily destroy barrels, tracks, and machine guns with ease as well as being able to shred light vehicles.

{{main|Hydra 70}}

The LAV-AD also has access to Hydra 70 M247 rockets with a researchable modification. This modification gives the vehicle an additional weapon set-up, replacing the Stinger pod above the main gun with a Hydra 70 rocket pod with 19 rockets, similar to those found on [[AH-1 (Family)|AH-1 Cobras]] and [[AH-64 (Family)|AH-64 Apaches]]. The Hydras are fired as a secondary weapon.

{{main|FIM-92 Stinger}}

The LAV-AD also comes with [[FIM-92 Stinger]] missiles. The missiles are IR guided, meaning they require a lock-on before firing. The vehicle has FIM-92Es by default and can unlock FIM-92Ks as a later modification. These are the same Stinger missiles used by the [[Ozelot]] in the German tech tree and function the same way. The missiles are launched as special weapons.

== Usage in battles ==

''Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).''

=== Pros and cons ===


'''Pros:'''

* Has access to Hydra 70 rockets
* The 25 mm GAU-12U cannon shreds any air vehicles in its range
* The 25mm GAU-12U has no tracers making enemy planes/tanks harder to notice your location when firing
* Highly mobile thanks to its light weight and is also amphibious
* Can carry up to 16 SAMs if you choose to not have Hydras
* Has access to 2nd generation thermal sights for the gunner
* Has optical tracking meaning air targets will not receive RWR pings when locked onto
* Comes with smoke grenades stock
* Laser rangefinder automatically adjusts the sights
* Not equipping Hydras enables the Stingers to be fired in relatively quick succession with no reload
* Can fire Stingers while on the move

'''Cons:'''

* The SAM has only a maximum overload of 10G which may prove difficult against planes with high manoeuvrability
* Long reload for the 25 mm gun
* Bringing the Hydra rocket pod reduces the number of available Stingers and gives them a lengthy reload time after 4 have been launched
* Penetrable by heavy machine gun fire and is prone to overpressure damage
* Shorter missile range and lacks a search radar when compared to its contemporaries like the [[Roland 1]], [[FlaRakPz 1]], and [[XM975]] at the same BR
* MAW detects missile launches and Stingers are prone to being diverted by flares
* No proximity-fused ammunition
* Hydra rockets are hard to aim due to their low velocity and do not work properly with the laser rangefinder
* Low sight FOV and relatively high zoom levels makes it hard to use against multiple targets up close
* 25 mm gun is inaccurate at longer ranges

== History ==

=== [[wt:en/news/7598-development-lav-ad-revolving-firepower-en|Devblog]] ===

Development of the LAV-AD began in 1987 after a contract was signed with both the FMC Corporation and General Electric to design a SPAA variant for the LAV-25 for the USMC. Both companies began developing a system based on the USMC requirements that it had to be armed with a 25 mm cannon and possess provisions for mounting Stinger missiles and Hydra-70 rockets. While the FMC company opted to outfit their design with the same M242 cannon used on the base model of the LAV-25, General Electric decided to go for the GAU-12 'Equalizer' Gatling style rotary cannon.

Having reviewed both prototypes, the USMC decided to procure General Electric's design, placing an initial order for 125 vehicles to be produced. By 1996, the LAV-AD had formally been adopted into service. Despite the initial plans to produce over 100 vehicles, only 17 were actually manufactured due to funding issues. In 1998, the final unit was delivered to the USMC and further development of the vehicle was discontinued due to high maintenance costs. Among other operations, the LAV-AD was used in combat action in Iraq.

U67347324: /* Pros and cons */ adats missile can overpressure tanks

{{Specs-Card
|code=us_adats_bradley
|images={{Specs-Card-Image|GarageImage_{{PAGENAME}}.jpg}}
}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} American tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.89 "Imperial Navy"]].

The ADATS is essentially an [[M3 Bradley]] with a heavily modified turret. The crew was moved away from the turret and controls it via interface in the back of the tank. The turret is fully automatic and now carries two enormous missile racks, a radar and the same old gun is tweaked to fire three times faster.

While designations for this tank go all over the place, the ADATS can be simply called a multi-purpose tank, as it can fight fast jets and heavier tanks alike with missiles, while dealing with lightly armoured tanks and slower aircraft by using a gun and/or missiles.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}


'''Armour type:'''

* Aluminium alloy 5083 (Hull front, turret)
* Aluminium alloy 7039 (Hull sides, rear, optics)
* Rolled homogeneous armour (Hull plates)

{| class="wikitable"
|-
! Armour !! Front (Slope angle) !! Sides !! Rear !! Roof

|-

|-
|}

'''Notes:'''

* Suspension wheels are 10 mm thick
* Tracks are 15 mm thick

The ADATS boasts the same protection as the regular [[M3 Bradley]] hull-wise, with one key difference being that the side armour is thinner by 19 mm. High-calibre machine guns such as the 20 mm's on French MBTs will easily penetrate the sides and at times even the front part of the hull. It's not advisable to use the ADATS as a front-line vehicle but rather as a second-line support vehicle by setting up in key-points around maps.

[[File:Bradley ADATS Side-view.jpg|thumb|300x300px|The gap between the Loader/Gunner and the Driver visualized with a green square. Also, you can see the unmanned turret.]]
One upside for the ADATS is that the turret is completely unmanned, meaning that any Armour-piercing shells will over-penetrate with no injuries to the crew at all (be aware that explosive shells can cause the rockets to explode and instantly destroy the vehicle). The three crew members are situated in the hull with a massive empty space between the loader/gunner and the driver when approached from the side. Every enemy you face will most likely over-penetrate that section and do minimal damage to the vehicle itself.

Overall, the ADATS can be quite a 'meme' vehicle as it can sometimes sustain 5-7 direct hits even centre-hull, seeing as most rounds just pierce and exit the armour without generating shrapnel, over-penetrating and forcing enemies to snipe for crew members.

{{Specs-Tank-Weapon|2}}

{{main|M242 (25 mm)}}

The main armament of the ADATS is the M242 25 mm automatic cannon, the same as found on the M3 Bradley, but enjoys a faster rate of fire (500 rounds per minute, compared to the Bradley's 201 rounds per minute). When stock, like most AA vehicles, it starts with a belt of equal parts armour-piercing and high-explosive, though it is worth mentioning the AP rounds are sabot rounds with 101 mm of penetration at 100 meters against flat armour. This allows it to easily and effectively take on both air and ground threats simultaneously without needing to worry about ammunition costs. However, should you wish to use this vehicle in a dedicated anti-aircraft role, you can unlock a belt with three parts HE to one AP in Tier I modifications. This must be unlocked in order to unlock M791, the AP belt. With this belt, dealing with any and all lightly armoured vehicles and even quite a few of the MBTs is possible from the side. In regards to how much you should take, you may as well take a full ammunition load. At any range, this vehicle can and will be penetrated by any vehicle that looks in its general direction, so it's not like your armour is going to stop you from being ammo-racked by fin-stabilized sabot anyway. Also, due to the cannon's high-ish rate of fire and ammunition count of 600 rounds, it's worth taking as much as you can carry.

=== Additional armament ===
{{Specs-Tank-Weapon|1}}

{{main|MIM146}}

Secondary armament of the ADATS (or primary, depending on how you choose to play it) are the MIM146 dual purpose guided missiles. You can effectively use these against any target you can point them at, due to the facts that they air-burst near aircraft, usually one-hit killing them with the 7.86 kilos of TNT equivalent, and have 900 mm of penetration against armoured targets. With a velocity of 1,200 m/s, aiming these things and tracking moving targets isn't an issue whatsoever. You point, you click, and the target usually dies in a single hit. In the event that, by some miracle of God himself, the target persists in clinging to their life, you can fire the MIM's as fast as you'd like to, meaning follow-up shots are quick and easy, and with the aforementioned 900 mm of penetration, anything you shoot these at WILL be penetrated, unless the angle of impact is extreme.

== Usage in battles ==

'''Stock Gameplay:'''

As with any vehicle, the ADATS finds itself at a disadvantage while stock. Without access to the thermal vision devices, players will need to be more alert in order to spot enemies. While other modifications like artillery or smoke grenades can be helpful, the lack of thermals is a much larger issue. However the ADATS is relatively well off stock compared to most high tier vehicles, as the stock 25mm belts include APDS rounds, and the radar is capable of spotting air targets for you.

'''Spaded Gameplay:'''

The ADATS is an excellent multi-purpose support vehicle when spaded. Being able to target both enemy tanks and enemy aircraft, it can be a great tool for the team. However, there are some limitations to the vehicle, namely the low missile count and lack of armour. While survivability is decent due to the empty turret, the armour is very thin and the missiles can sometimes explode when hit. This means that the ADATS does best sitting behind friendly tanks, in a support role. Additionally the missiles can run out quickly, as there are only 8 to engage both air and ground targets. ADATS players should try and conserve their missiles, as they are very valuable.

'''Close Range Engagements:'''

The ADATS is capable at close range, but it will die very easily to enemy fire. The 25mm bushmaster autocannon can penetrate the side armour of most enemy tanks, but it will not disable the enemy as quickly as their large cannons are capable of killing the ADATS. The ADATS missiles can be useful at close range as well.

'''Long Range Engagements:'''

The ADATS is more capable at long range, where it can rely on thermal vision and the very fast ADATS missiles to disable enemy targets. The only issue at long range is the low amount of missiles, so shots should be taken with care. Additionally, the ADATS can be quickly disabled if the hull is exposed, so staying hull down is advised. The radar should also be turned off and on as needed, as it provides a good indicator of where you are for enemy ground vehicles, but is very useful in spotting air targets.

'''Gameplay summary:'''

The ADATS is an excellent support vehicle, able to defend teammates from both enemy air and ground threats. The ADATS missiles are excellent at disabling any target, although the low ammo count should be considered. The ADATS is also capable of locking an enemy aircraft without alerting their RWR, by turning off the radar. One must take excellent care in their method of positioning.

=== Pros and cons ===


'''Pros:'''

* Has access to 8 x multi-purpose missiles, can effectively eliminate both aircraft and tanks
* Missiles can penetrate up to 900 mm of armour
* Missiles are incredibly fast with a speed of 1,200 m/s
* Powerful 25 mm cannon with good APDS for ground targets and HE ammunition for use against air targets
* Gunner operates the turret and weapons from behind protective hull instead of being in the turret itself
* Built on the chassis of M3 Bradley- good mobility and acceptable armour
* Modifications are researched fairly quickly
* Effective radar with good range
* Can lock on to aircraft with the radar disabled as the ADATS tracks using an electro-optical targeting system, making sneak attacks easy
* Missiles can even be fired without lock on and retain their proximity fuse against aircraft
* Can overpressure tanks with atgm due to 7.8 kg tnt equivalent

'''Cons:'''

* Thin armour is not effective against larger cannons
* High profile makes it hard to conceal, it is easily spotted
* Can be destroyed if directly rammed by a plane
* The three crew members are all situated within the hull, and can all be rendered unconscious if a shot penetrates the hull
* The 25 mm autocannon can't reliably penetrate MBTs frontally
* The missiles are essentially giant exposed ammo-racks
* Lack of stabiliser makes firing on the move difficult and increases the time to aim the weapons when suddenly braking
* Missiles cannot be fired on the move, only guided
* Vulnerable to the [[Damage mechanics#Overpressure|overpressure]] mechanic

== History ==

The ADATS was developed at the end of the 1980s as a general-purpose weapon capable of bringing down low-flying airborne targets as well as armoured opponents. Hence the abbreviation: Air Defence Anti-Tank System. The system was comprised of radar for detecting and tracking targets, a complex radio kit for coordinating multiple vehicles, and eight MIM-146 guided missiles in transport and launch containers. The US Army version was built on the Bradley IFV chassis and fitted with a 25 mm autocannon. Notwithstanding the fact that it was selected after a US Army competition for the Forward Area Air-Defence program, it was found to be excessively expensive to manufacture and never made it to serial production on the Bradley chassis.

M56

U67347324: /* History */ the m56 got a recoil nerf making its recoil on the low-medium side

{{Specs-Card
|code=us_m56_scorpion
|images={{Specs-Card-Image|GarageImage_{{PAGENAME}}.jpg}}
}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} American tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.63 "Desert Hunters"]].

Though one of the lightest tank destroyers in the game, its 90 mm gun gives it a very powerful punch, especially when using the HEATFS round, which can penetrate up to 320 mm of armour.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}

Fitting the definition of a glass cannon, the M56 has virtually no armour to speak of, as the majority of the tank comprises structural steel not meant to protect the crew and has a weak armour modifier (x0.45 KE), which renders it near useless in protecting internal components from incoming fire of any calibre, with the exception of high-angle impacts from rifle-calibre rounds. This description also applies to the only armour plate found on the entire tank, the gun shield, as the 5 mm thick plate with 12 mm of bullet-proof glass will only be able to stop rifle-calibre bullets from mid to long ranges.

The crew consists of only 3 members: a driver on the left side of the gun breech, the gunner on the right side of the gun breech, and the commander sitting rather casually behind the driver. If the tank is spotted and takes fire, expect the commander to be the first crew member down, since he is the most exposed among the three, sitting far away and above the gun shield. This will also impact your reload rate.

Overall, survivability is very low and it is advised to take precautions not to take any fire from the opposition, making use of terrain and mobility when the battle gets heated. Any HE shell will destroy your vehicle, with the overpressure mechanics. This makes chemical energy and artillery shells as well as rockets deadly for your vehicle.

'''Armour type:'''

* Structural steel
* Rolled homogeneous armour (Gun shield)
* Bulletproof glass

=== Mobility ===
{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=284|rbMinHp=177}}

Where the M56 lacks in armour, it easily makes up for in mobility. Its light weight and decently powered engine gives it a great power-to-weight ratio that lets it propel to top speed easily, even when stock. You'll want to use this to gain access to favourable positions at the beginning of each match. When your position is compromised, seek a retreat using its excellent reverse speed of -20 km/h and plan ahead your next route.

[[File:M56 horizontal gun displacement.png|right|thumbnail|Gun horizontal displacement of the M56|200px]]
The 90 mm M54 is the M41 gun available on the [[M48A1]] but equipped with a recoil system, which is why they have the same available ammunition choice. The cannon's accuracy drop is noticeable as soon as 800 m distance and a handicap over 1,000 m unless you fire at huge targets (Ferdinand, Jadgtiger, Tiger II, etc.). Some stabilized ammunition, such as HEAT-FS, do not suffer as much from the accuracy drop over distance.

The rotation speed of the gun is very slow compared to other tanks at the same rank or battle rating who can aim their gun in average 2 to 3 times faster than you do. Which means your targeting process will be long if you aim to be accurate. Also, any movement of your hull will make you restart your targeting process from scratch, which limits greatly your possibility to overextend, even after a successful first disabling shot.

Additionally to having a limited gun rotation on the horizontal axis, that displacement is asymmetrical due to the driver position limiting movement to the right side. This can make the tracking of a target difficult as the gun quickly reaches a stop. Take that constraint into account when positioning your hull at a firing spot.

Your recoil also is a handicapping feature: your hull being very light, it can not absorb much of the recoil power (even with the huge damping cylinders on the gun). Every shot taken throws your gun off target after firing, forcing to restart your targeting process or even reposition your hull. Using the "sight distance control" feature can help mitigate that aspect but any movement of the mouse during the recoil phase will nullify the sight setting.

==== Ammunition ====
The M54 cannon offers 5 types of ammunition to choose from: APCR shots, APCBC rounds, HEAT-FS rounds, HESH shells, and HE shells.

The '''M332 APCR''' shells are the basic rounds that you'll utilize when you first play your tank. Like any other APCR shell, with knowledge of the opposition's internal components such as gunner/driver locations and ammo racks, it is very useful against heavy foes with low-angle slopes in their armour profile. But, it is very lacking in post-penetration damage. Though they are free to use, players may find the lack of post-penetration damage unfavourable, especially for a glass cannon who can't risk staying exposed for very long trying to pick apart an armoured foe.

The '''M82 APCBC''' shells are probably the first shells you'll unlock and will provide some relief if you've grown tired of the APCR's low post-pen damage. Like any other APHE, they possess good penetration at close to mid range with exceptional post-penetration damage for dealing with moderately armoured targets like many of the medium tanks you'll encounter at your battle rating. As soon as you unlock these, start carrying these as your standard round against most tanks while carrying a few of the above APCR for heavier foes, at least until you unlock the HEAT-FS round.

The '''M431 HEAT-FS''' should be '''the''' round you want to rely on to take care of most armoured foes you come across. Combining the best muzzle velocity, the greatest penetration, especially at long range, and decent post-penetration damage makes this the superior round to use in any mid-to-long range engagement. At close range or in ambush situations, with this shell being your loaded round, you will most likely cripple any target you may encounter. It may then be best to switch to APCBC or HESH (depending on the vehicle type) as a follow up to finish off the surviving target, unless the target still presents itself to be very armoured from your angle of fire (like the [[Maus]] or most heavies from the front). Especially so if you're conscious about your ammo bill after the battle as HEAT-FS are not the cheapest option.

The '''T142E3 HESH''' are an advanced high-explosive round that's capable of penetrating thick armour, even when it is highly-sloped. If you know your target possesses not a single plate of armour greater than 100mm, then these are the rounds to use to wreck them at any range, as these are equally effective against a valid target, including many medium tanks, any light tank and SPAA, and even some heavy tanks that rely on angles rather then raw thickness like an [[IS-3]] or [[AMX-50 Surbaisse]]. Just be sure to aim away from the tracks and suspension, as these modules can easily absorb any damage caused by HESH.

The '''M71 HE''' are just like your typical medium-calibre HE round, good against unarmoured targets like exposed crew members, hull-breakable vehicles, and air targets (should you be able to hit them), but not very useful outside of that. Though this is a free round with slightly better velocity (making it easier to use at long range), favour HESH instead when you can as it carries nearly as much of a payload and has increased versatility against more targets.

One last ammo type to mention are the '''M313 Smoke''' shells. While not particularly useful for the role the M56 typically fills, they can still have good effect in long-range conflicts where a smoke to the face of an experienced enemy sniper can buy you or your allies time to bypass them in favour of a retreat or advancement towards the objective.

Overall, with all shells unlocked where you'll be employing mid to close range tactics, the typical recommended ammo composition can look something like this: 12 HEAT-FS, 4 APCBC, 5 HESH. For long-range engagements where you'll be playing more of a sniper role, it's best to forgo the APCBC in favour of bringing as much HEAT-FS as you can while throwing in a couple of smokes, though the smokes are optional. With this the recommended ammo composition for long-range engagements will look more like this: 20 HEAT-FS, 7 HESH, 2 Smokes.

* The ammo racks on the M56 are 3 staggered rows of 10 (top), 9 (middle) and 10 (bottom) totaling 29 shells.
* The first rack to be depleted is the top row, then the middle row and finally the bottom row.
* To go into battle at full capacity, pack 29 shells (bottom row: 10 + middle row: 9 + top row: 10, with 1 shell in the breech taken from the top row).
* To go into battle with the first rack depleted, pack 20 shells (bottom row: 10 + middle row: 9 + 1 shell in the breech).
* To go into battle with the first and second racks depleted, pack 11 shells (bottom row: 10 + 1 shell in the breech).
* To go into battle with the 3 racks depleted, pack 1 shell (1 shell in the breech).
* Recommended ammo load is 20. Carry a full load of 29 rounds only for large open maps like [[Kursk (Ground Forces)|Kursk]], [[Fulda (Ground Forces)|Fulda Gap]] and [[Maginot Line (Ground Forces)|Maginot Line]].

== Usage in battles ==

The M56 Scorpion is a fast, light tank destroyer with very little armour to speak of.

A rapid volley from an enemy machine gun will knockout the three crew members with ease, if not carefully concealed. Its 90 mm M54 cannon is very able to disable enemy tanks at Rank IV. It is able to perform various destruction missions utilising various tactics. An M56 Scorpion is a dedicated airborne tank destroyer with airborne vehicle-based performance. The scorpion has a very stable and fast rate of acceleration on any terrain with a top speed of up to 28 MPH (45 km/h). With its high speed, it is very tempting to charge towards the capture point. When in a situation where a single enemy tank is present, unprotected, uncovered and separated from the opposing team. A rampaging Scorpion will be able to close in, then blow it up to kingdom come. However, caution must be undertaken throughout.

Be wary that any tank, even if only armed with a machine gun, is capable of knocking out the M56 due to the exposed crew. One particular enemy to keep an eye out for is the [[ASU-85]]. It's a complete Soviet equivalent of the Scorpion. Its stock BR-372 APCBC-HE is hopeless against a Scorpion since it will always overpenetrate it & be unable to explode inside its engine or gun breech. Meanwhile the M82 APCBC-HE has the opposite effect against it, as the ASU-85 has 45 mm armour just like the [[T-34-85]], which was a big mistake. Even with inferior penetration, an M82 still has 1.5x more explosive warhead. Given enough penetration, it will always be able to cause it to explode frontally without much effort. Take a grain of salt when firing at the ASU-85 from its flank, since the M82 will also overpenetrate away. Loading the M71 HE is much better, since the explosion will spam the ASU-85's interior all over the place. Or if already loaded with M82 & an ASU-85 is approaching while showing its flank, aim for the engine to prevent it from recovering & escaping. Then blast it away.

===Game modes===
While the Arcade Battle environment is not favourable due to the marker system easily spotting the M56, it can still perform in flank and surprise attacks if employed properly. It still can snipe from far away & make score against some targets when the M431 HEATFS is unlocked. Be aware that many light tanks can hunt it down if caught in firing range, particularly the [[M41A1|M41A1 Bulldog]] and [[T92]].

'''Flanking/Sniper'''

The battle environment is more favourable in Realistic and Simulator Battles. It can completely perform full flanking manoeuvres even when stock, it can also snipe from far-distance without getting spotted easily. Using both tactics will guarantee a complete concealment from the enemy, while being able to fire M82 APCBC shells at them. Closing in to the enemy is only viable if the enemy number has been completely depleted and/or are unable to insert reinforcements to cover their team.

Closing in, the Scorpion can out manoeuvre and outflank most, if not all enemy vehicles at its BR. When it is unable to flank due to tight enemy formation across the map, sniping is the best option.

It is recommended to Load: M431 HEATFS or M82 APCBC if the enemy armour is insufficient to withstand such rounds. I.e. [[T-34-100]]). The reload time can help it to outgun any opposition, to withstand its sustained rate of fire. Especially if it is equipped with an Ace crew, which can reload around of 7 seconds. Also, try to use an ambush tactic. It can annihilate a whole team if used by a skilled player.

'''Ambush'''

In Realistic, the great speed, manoeuvrability, and minuscule size of the M56 is nearly perfect for the role of an ambush predator. The M56 is capable of driving stealthily behind enemy lines completely undetected. However, in city environments, the M56 must practice stealth much more, as to not alert any enemy.

Once in position, hopefully within a circle of bushes or rubble, the small tank destroyer can capitalize on its scouting ability, revealing most of its enemies' positions. The use of the main cannon will also thin out the enemy defense for the M56's team's main force.

However, firing the main cannon more than thrice before moving locations will most likely alert the enemy. Therefore, when the M56's position eventually does get compromised, its cannon and excellent acceleration can both take out any unwanted investigators, and carry itself nimbly into another hiding spot. It is recommended to load mainly on M82 APCBC shells for attacking the unsuspecting sides of the enemy and a few M431 HEATFS rounds for any sticky situation that the M56 might get into whilst getting to or from a hiding spot.

=== Pros and cons ===


'''Pros:'''

* Very small profile (68% visibility)
* Excellent mobility & manoeuvrability on all terrain (45 km/h top speed & great acceleration, 20 km/h reverse speed)
* A practically airworthy vehicle- ''very'', ''very'' light (7 tons)
* The same 90 mm gun and ammunition selection as the [[M48A1|M48A1 Patton]]
* Considering its recoil, the gun is surprisingly accurate
* Quick reload time
* 3 varieties of very capable shells
** Stock APCR shell has a big penetration power
** Destructive APCBC with explosive filler can take out enemies with a single shot
** HEATFS can punch through 320 mm of armour

'''Cons:'''

* No armour
** A shot through the bulletproof glass will knock-out 2 crew members and instantly disable the vehicle
** High chance to catch fire when shot in the frontal hull
** Affected by the overpressure mechanic (large HE shells will outright destroy the M56)
** Hopeless if it is immobilised
* Open-topped vehicle with all crew members exposed
**vulnerable to strafing attacks from planes
* Easily tipped over because of its light weight
* Top speed is limited at 45 km/h. While boasting excellent acceleration, it will be outrun by other light vehicles on open field
* Does not climb hills well unless approached with good speed
* APCR as stock shell; unable to cripple a tank even from flank with only a shot
* Gun has very slow traverse and elevation, meaning that it takes a while to readjust after taking a shot

== History ==

===Development===
During World War II, the constant problem for the US Airborne divisions is that their anti-tank power was very minimal in the front lines. Though there were attempts to improve their firepower with towed anti-tank guns or airborne tanks like the [[M22|M22 ''Locust'']], the former proved too cumbersome and heavy while the latter proved too under-powered and weak. Thus, development began in April 1949 for a very lightly armoured vehicle to mount a hard-hitting gun with heavy emphasis on firepower, speed, and with as little weight as possible. This evolved into the development of a self-propelled 90 mm gun and the project was taken up by the Cadillac Motor Division of General Motors. The pilot vehicle developed were designated ''T101''.<ref name="ZalogaM551">Zaloga Steven. ''M551 Sheridan: US Airmobile Tanks 1941-2001'' Great Britain: Osprey Publishing Ltd., 2009</ref>

The first models were completed in 1953 and were tested in 1955. It was approved for service in 1958 and designated as the '''M56 90mm self-propelled gun''', or by its nickname '''"Scorpion"''' and its acronym '''SPAT''' ('''S'''elf-'''P'''ropelled '''A'''nti-'''T'''ank). It's main selling point was being light enough at only 7 tons to be lifted by helicopter or carried onto aircraft, allowing for parachute drops. As a rather specialized vehicle, it wasn't produced in large numbers, with only 150 units built from the Cadillac production line from 1953 to 1959.<ref name="ZalogaM551" />

===Usage===
The M56 Scorpion was issued out to airborne and anti-tank units from 1958 to the early 1960s. As a defensive weapon, the M56 Scorpion was never meant to venture out to seek and destroy enemy tanks, but its lack of armour was still criticized by its crew, what with only a simple gun shield blocking the crew from getting shot by even small arms. The lightness of the vehicle was also bad for the extreme recoil of the 90 mm M54 gun, which would lift the entire vehicle off its front wheels.<ref name="ZalogaM551">Zaloga Steven. ''M551 Sheridan: US Airmobile Tanks 1941-2001'' Great Britain: Osprey Publishing Ltd., 2009</ref> An informal manual even recommends that when firing, the commander and loader should step off the vehicle to avoid being harmed by the lurching vehicle. The M56 Scorpion served America in combat during the Vietnam War in the 173rd Airborne Brigade, with 17 vehicles organized into three platoons. It served as a defensive role in most of American foreign bases until the advent of the anti-tank missile launchers such as the TOW, which proved more potent than the Scorpion, and was replaced in the late 1960s and early 70s.<ref name="ZalogaM551" />

The M56 Scorpions were also given out in limited numbers, with Morocco given 87 vehicles and Spain obtaining 5 in the Military Aid Program. Morocco used the Scorpions in the Western Sahara War, being the only foreign user of the M56 Scorpions.

===Survivors===
At least 18 intact M56 Scorpions survive in the United States today, mainly in museums and in private collections.
