== Description ==

[[File:GarageImage_SU-100.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a Rank {{Specs|rank}} Soviet tank destroyer {{Battle-rating}}. It was one of the first vehicles introduced in the opening of "Ground Forces" in Update 1.41. Featuring the [[D-10S (100 mm)|100 mm gun]] with a strengthened design from the [[SU-85]], the SU-100 can prove a menace to anyone on the other end of its gun.

The SU-100 is a classical casemate tank destroyer and as such has a fixed forward gun for its main armament, not too unlike the [[SU-85]][[SU-85M|(M)]] tank destroyers. This gives the SU-100 a preference towards a defensive playstyle than an offensive one. As such, it is best to play the SU-100 in a supporting role, firing at distant enemies and ambushing them rather than facing them head-on. The SU-100 boasts high firepower and long effective range due to its 100 mm armament. The gun is able to penetrate armour similar to the 122 mm on the [[IS-2]], but also a faster reload rate while retaining suitable post-penetration damage to devastating enemy tanks. As such, the SU-100 can lay in wait hidden in an open field and confidently attack enemies up to 1,000 meters away.

The SU-100 does not look very different from the Rank III [[SU-85M]] tank destroyer, the only big external difference is the large 100 mm D-10S gun extending from the body, significantly bigger than the 85 mm D-5S gun. Though external difference is minimal, the performance in-game is big enough for a whole rank. The 100 mm gun boasts penetration levels along the line of the 122 mm, but with much faster muzzle velocity and reload speed. Aside from that, everything else is the same as the SU-85M. Gun elevation and depression is the same as +20°/-3°. The armour on the SU-100 is 75 mm sloped frontal armour. The engine and weight are also the same.

With all these similarities, those familiar with the SU-85 series will feel at home with the SU-100, with the exception that a majority of the enemies in the BR bracket can effortlessly knock out the SU-100 with even a glancing shot.

== Usage in the battles ==

The SU-100, as a Rank IV vehicle with a battle rating of 6.3, can be effortlessly defeated by a majority of the enemies faced at the BR bracket. As such, it is most important that the SU-100 makes the first, damaging shot before the enemy could get a shot first.

* Panther [[Panther A|A]],[[Panther G|G]],[[Panther F|F]]: Though the Panther's 75 mm gun can penetrate the SU-100's front armour with little difficulty, the 100 mm gun can penetrate the Panther's front glacis plate at quite a distance (>500m). Thus, getting the first shot off will turn the battle situation towards the SU-100's advantage.
* Tiger [[Tiger II (P)|(P)]] and [[Tiger II (H)|(H)]]: The front glacis of the Tiger II is impervious to the 100 mm, but the turret cheeks are still a major weak point that the gun can easily penetrate. At closer range, the lower glacis is also a weak point on the front area. If the Tiger II decides to traverse its turret slightly away from towards the SU-100, the 100 mm also has enough power to penetrate through the Tiger II turret side rather easily.
* [[IS-2]] ([[IS-2 (1944)|1944]]): The IS-2 is easily disposable by a good firing on the front glacis, though the 1944 version requires careful aiming on the front glacis, thus it is better to aim at the lower glacis for an easier time at penetrating. The turret cheeks are also easy to penetrate like other heavy tanks.

=== Pros and cons ===

'''Pros:'''

* The 100 mm D-10 gun from the T-54 series at 6.3
* Stock shells have high penetration and explosive filler
* Can easily one-shot many tanks
* Great top speed and manoeuvrability (56 km/h)
* Decent ammo count

'''Cons:'''

* Although the front armour is sloped, it's thin and easily penetrated
* Bad gun depression of 3 degrees
* Can be easily taken out in one shot due to the cramped internals
* Weak armour in overall
* Large profile and long cannon make the tank hard to conceal

== History ==

===Development===
This tank destroyer takes its lineage from its predecessor [[SU-85]]. The SU-85's introduction with its 85 mm D-5 cannon made it a lethal weapon against German tanks, giving it much better firepower than the current T-34 with the 76.2 mm F-34 guns. However, the SU-85 became redundant when the T-34 began to upgrade into the [[T-34-85]], which contains the same 85 mm gun as the SU-85. No longer having the advantage in firepower, the SU-85 was discontinued, but the role of a self-propelled gun was still required to support the armoured forces.

It was decided to up-gun the SU-85 model with a much bigger cannon. Lev I. Gorlitsky, the chief designer of Soviet medium self-propelled guns, began the development of improving the SU-85. It was decided that the new cannon will be of 100 mm in calibre, and work started on developing the prototype in February 1944. In March, the prototype named "Object 138" was made for testing, mainly by trying many different 100 mm guns to see which would prove most effective. It was decided that the 100 mm D-10 gun produced by Fyodor F. Petrov's design bureau, which was an adapted S-34 naval gun, was to be used as the main armament of the self-propelled gun, now named the '''SU-100'''.

While the vehicle is essentially a SU-85 reworked to mount the larger 100 mm cannon, the SU-100 body has some major improvements compared to its predecessor. Armour on the front is increased from the regular 45 mm to 75 mm, the commander's workplace was enlarged into a small sponson on the right side of the hull with a commander's cupola, which increased his combat effectiveness. Two new ventilator units were also installed for increased ventilation of the gun's propellant gases. Production started in September 1944 and continued until some time in 1947 with a total of 2,335 units produced.

===Combat usage===
In its introduction in the last few months of World War II, the SU-100 proved to be a very successful tank destroyer. The 100 mm D-10 gun could penetrate 125 mm of armour at 2,000 meters away, against the Panther, it could take it out from 1,500 meters away easily. Most of the SU-100 in service saw action in Hungary in March 1945, most notably in the German offensive Operation Frühlingserwachen (Spring Awakening). Although never intended for infantry support, the SU-100 even saw action in the Battle of Berlin in the close-quarters combat of urban warfare as its 100 mm gun was very good against heavy fortifications, but the lack of any machine guns has the vehicle work in cohesion with infantry or aircraft.

After World War II, the Red Army retained the SU-100 for a few more years until retiring them to reserves in 1947, still existing to this day. The SU-100 was given out to Warsaw Pact allies such as Egypt, Angola, Cuba, China, and Czechoslovakia. The SU-100 saw service in many Cold-War conflicts such as the Korean War in 1950, Vietnam War in 1955, Suez Crisis in 1956, the Six-Day War in 1967 and the Yom Kippur War in 1973. Some were modified to adapt to the sandy environment of the Middle East, these were designated the ''SU-100M''. These exported SU-100s continue to see service up to today in some countries, but most replaced it by 1970s. One of the most recent usages of the SU-100 is in Yemen during the Yemen Civil War of 2015.

=== In-game description ===
"In connection with the increased armour of new enemy heavy tanks, it became necessary to create a self-propelled gun more powerful than the SU-85. Mass production of a new SPG under the designation SU-100 began at UZTM in August 1944. The engine, transmission, undercarriage and many other key parts from the T-34-85 tank were used in its design. It was armed with a 100 mm D-10S cannon with a 56 calibre barrel length. This weapon perfectly combined a high rate of fire with good ballistic characteristics. Its armour-piercing shell could penetrate 160 mm thick armour from a distance of 1000 metres. The vehicle had a standard design, with the driving compartment in the front, the fighting compartment in the middle and the engine compartment in the rear. Above the commander's place, the cabin's roof contained a fixed command cupola with five observation slots for all-round visibility. The command cupola's hatch housed an MK-4 observation instrument and rotated on a bearing.

The SPG was manufactured between 1944 and 1947, and 2,495 SPGs of this type were produced during the Great Patriotic War.
The SU-100 was first deployed in battle in January 1945. The SPGs showed their worth and earned a reputation as a reliable and powerful combat vehicle.
The vehicle also inherited negative aspects from its base tank, such as its outdated suspension construction, its fuel tank positioning in the fighting compartment, and its unfavourable layout for an SPG. The SU-100's barrel length was even greater than that of the SU-85, making manoeuvring difficult on rough terrain and in urban areas.
After the war, the vehicle was modernised numerous times and remained in service in the Soviet Army for several decades. These SPGs were supplied to the USSR's allies and took part in a range of local post-war conflicts."

ASU-57

U15034886: added engine power and power-to-weight for upgraded arcade

{{Specs-Card|code=ussr_asu_57}}

== Description ==

[[File:GarageImage_ASU-57.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Russian tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.59 "Flaming Arrows"]]. It is a tiny, mobile 57 mm gun carriage akin to the [[ZiS-30]].

The ASU-57 is a tiny, open topped, turretless SPG armed with a 57 mm gun with good penetration. It is famously one of the smallest tracked vehicle in the game, weighing only 3.3 tons. Its complete lack of armour makes it extremely vulnerable, its only defense being its small size, making it extremely difficult to notice, let alone hit. It has very good speed and excellent maneuverability, being very nimble for a turretless tank destroyer. The 57 mm gun starts with solid shot rounds, which is troublesome as each shot will make the firing position more apparent. For this reason it is recommended to research the APHE rounds and adjustment of fire to reduce the number of shots needed to destroy an enemy.

The ASU-57 is very difficult but very rewarding and fun to play, and it is not recommended for arcade battles, as its primary advantage, stealth, is lost. The ASU-57 is a master of stealth, famed and beloved by the community by its ability to sneak up on tanks by using its extremely small size. When using the ASU-57, objects that other tanks would ignore or simply drive over are capable of completely hiding the vehicle, making ambushes and surprise attacks the specialty of the ASU-57. This size comes at a cost, however, as the ASU-57 has barely more survivability than a Soviet AA truck.

== Usage in battles ==


The ASU-57 is best used as an ambusher/flanker, executing surprise attacks from unexpected locations other vehicles would struggle or be unable to reach. The ASU-57 is incredibly short, and by driving up next to an enemy can render the vehicle completely safe, as almost no vehicle has enough gun depression to reach it. For this reason it is recommended to only go after isolated vehicles, as an enemy teammate will be able to assist their ally by destroying the ASU-57. For the maximum efficiency of this tactic, knock out the driver of the enemy vehicle, then rush up to their side before they can bring their gun to bear. Once this is done, try to ammo rack or pick off their crew before they can recover. with the addition of NVD's to the ASU, you can be quite the foe in a night battle if the situation ever arises.

Literally any vehicle, be it ground or air, can destroy the ASU-57 within seconds if allowed to get it in their sights.

=== Pros and cons ===

'''Pros:'''

* Tiny size and very light weight
* Difficult to target at long range
* Easy to conceal. The tank can proceed to the other side of the map and not be seen by anyone
* Good speed and mobility
* Although very vulnerable to strafing by enemy planes, the vehicle can be easily concealed from their view (RB and SB)
* Very low profile makes it impossible to be hit by most enemy tank guns when right next to them
* Powerful 57 mm gun
* Access to APCR ammunition
* Access to NVDs
* Lowest ranked vehicle that has access to NVDs

'''Cons:'''

* Virtually no armour
* High top speed + no armour means the ASU-57 can destroy itself upon hard collision
* Lightweight and tiny size makes it easy to push around by enemy and friendly tanks
* Low ammunition count
* Crew can get knocked out easily by aircraft fire or artillery
* 57 mm gun can struggle to deal with angled armour
* 57 mm gun rarely can destroy vehicles with one shot
* Not suitable for AB players; this tank's main advantage is its small size, so having a big red marker does not play in the player's favour
* No defensive machine guns. SPAA can be a real threat, even at long range
* Crew are packed into the ASU-57, any damage will result in one or more knocked out crew member
* Prone to hull break
* Can really struggle to penetrate certain tanks it will face, such as Jumbos and Churchills
* Poor horizontal and vertical traverse of the gun
* Unsuitable for long range engagements
* Tall grass can hinder clear vision through the sight

== History ==

===Development===
In mid-1940s, sometime either late in World War II or post-war, a proposal was made to develop a vehicle for the airborne troops. The vehicle was to be a lightweight assault gun able to support the paratroopers by being transportable by air. The task was given to two design bureaus, OKB-40 headed by Nikolaj Astrov in Mytischi and the other to Anatoly Karvtsev in Moscow. Astrov designed his vehicle as the ''ASU-76'', armed with a 76 mm D-56T gun. The design ended up being too heavy and its armour way too thin for adequate protection and was cancelled. Kartsev's project was the ''K-73'' which was amphibious and used a 57 mm Ch-51 anti-tank gun as its armament. This was even more thinly armoured than the ASU-76 and was also cancelled.

In 1949, Astrov was able to continue work on his design, but with specifications that the vehicle be made lighter and use the 57 mm Ch-51 gun instead due to its anti-tank performances. The redesigned vehicle was labeled ''Object 572'' and passed the test phases in 1949. It was formally accepted for service as the '''ASU-57''' in 1951 and production lasted from 1950 to 1952 with amounts produced up to a thousand.

===Usage===
The ASU-57, as an airborne vehicle, was made to be air-dropped from planes and land via a rocket-assisted parachute. It was then crewed by its airborne crew and support the airborne troops in their operation. Each airborne division had 54 vehicles at its disposal. It proved successful despite its weak armour and small caliber as this type of vehicle was invaluable in the hands of airborne troops, able to use a mobile artillery vehicle behind enemy lines. The ASU-57 stayed in service in the Soviet Airborne Forces for around 20 years before being replaced by the [[ASU-85]].

The ASU-57 was also given out to the Soviet Union's allies from 1960s to 70s. Such included Egypt, East Germany, North Korea, Poland, Sahrawi Republic, Vietnam, Yugoslavia, and Ethiopia.
