m (→‎Pros and cons: Deleted the line about having to use your whole belt, as now you can reload partial belts on points. Which honestly makes the massive belt a good thing because you keep reloading constantly.)
(Added a general statement on survivability and armor, as well as improving the usage on combat areas. Added one more con, with less cannon shells per gun.)

The '''Semovente Contraereo da 20/70 quadruplo''' was an experimental self-propelled anti-aircraft weapon developed for the Italian Royal Army during World War II. The Royal Italian Army ordered the construction of a self-propelled anti-aircraft weapon in 1942 to be deployed in the North African theatre of operations and to protect mechanized columns, which were often targeted by the Royal Air Force (RAF) in the absence of genuine air defence. The hull of the [[M15/42]] was utilized as the foundation for the design to save time and materials. The tank turret was replaced with a polygonal welded open turret that housed a quadruple 20 mm Scotti Isotta Fraschini 20/70 Model 41 autocannon. The first prototype was completed in early 1943 and tested at the Centro Studi Motorizzazione dell'esercito. It entered service in March 1943 and was assigned to the VIII Reggimento Autieri stationed at Cecchignola in Rome, where it was captured by German forces. By April 1945, it was on active duty with the V SS-Freiwilligen-Gebirgskorps, which fought the final struggle against the Red Army in Germany in the Teupitz area.

Introduced in [[Update 1.85 "Supersonic"]], the Semovente Contraereo da 20/70 quadruplo is one of the greatest self-propelled anti-air vehicles for the lower ranks of the Italian Army ground forces. The Semovente Contraereo da 20/70 quadruplo, with a design similar to its German equivalent [[Wirbelwind|Flakpanzer IV "Wirbelwind"]], provides adequate air defences for friendly forces during engagements. In truth, this vehicle's cannons use the same ammo as its German equivalents. Even the heaviest planes are frequently brought down with only a few hits. However, the vehicle armour does not fully protect the crew, which might be a severe problem when numerous enemy planes are in the sky. As a result, it is critical to only fire when you are certain that the cannon rounds will hit.

The M42 Contraereo is based off the M15/42 hull with an opened top turret, surrounding the crew members. The gunner does have an exposed spot in the front, and if shown correctly to the enemy, can be machined gunned easily without them to have to fire their main cannon. The turret may protect you from small rifle caliber bullets, but 50. caliber and up, especially on the M4 Sherman will be able to penetrate your turret from anywhere, as it is generally weak against them. The hull armor is decent, still keeping the armor from the M15/42 hull, but don't expect to tank a lot of shots, as most of your enemies you will face at 3.3 will have better caliber weapons, with mostly encountering 75mm and Russian 76.2mm cannons. You may be able to bounce some smaller caliber shells like the 37mm cannons but don't rely on your hull armor as your turret will most likely be targeted by the enemy. You have a small crew count of 3 members, and with two in the turret, and having okay armor, you'll usually die in one hit.

In Realistic battles, the Quadruplo is best used in the support role when tank hunting, sticking with teammates, assisting them and potentially distracting the enemy. Your best bet of killing any tank, usually a Sherman, Cromwell or T-34, is from the side as the HVAP will pierce through their side armour, killing the tank. Light tanks such as M24s, Stuarts and Crusaders are able to be penetrated from the front, but usually this is only in close range engagements. T-50 and other slightly armoured light tanks will be tougher to kill, but you're still able to flank them. You can kill basically any SPAA you see, as you'll usually encounter trucks or armoured cars. Ambush and surprise tactics are good options to kill tanks effectively, as the enemy will stroll past you, usually showing their side armour. Aggressive playstyles are suggested to get the most out of the Quadruplo, similar to playing a Wirbelwind when tank hunting. Try not to expose yourself too much and move from cover to cover, as one hit from a tank shell, usually APHE, will knock you out in one shot, or the machine guns pierce your turret armour and kill both your gunner and commander. When it comes to shooting down planes in the Quadruplo, it is best to get their attention so they try to strafe you, or surprise them as they come closer to you, when you have a good shot as they won't have enough reaction time to evade your shots if they connect. Be mindful that you are open-topped, and you're less likely to survive a strafe run. It should also be noted that shooting continuously will sway the hull back and forth, which will make your aim go up and down.

Despite the guns having a high fire rate, and being close together, the Quadruplo has a lower ammo count per gun  with 12 with each gun, having a 48 in total loaded (essentially a discount Wirbelwind). It is easy to burn through it, so make sure you have a good shot on the aircraft you are trying to shoot down as you'll only have about 3-4 seconds of continuous fire before needing to reload.

The history of the M42 Contraereo began during the late stages of the Second World War. In the years following 1942, the Royal Italian army would set out a request for a mobile platform which could mount a special anti-air mount to bolster and provide protection to Italian mechanised columns. At the time they would be subject to very frequent air raids by the British RAF. Although they had some anti-air coverage, it was not enough for their needs. Ground units only really widely access to single 20 mm mounts, usually installed on armoured trucks.
+
* Low magazine count for the guns (12 ammo per cannon)
  
−
To save time and to reduce maintenance costs, the Italian army opted to go with the M15/42 tank to be used as the basis for the SPAA platform. The original turret would be removed and completely replaced with a new polygonal welded open turret, containing quadruple 20 mm Scotti Isotta Fraschini anti-air cannons. The turret could accommodate belt-fed munitions or clip-fed munitions. At the time this was actually one of the better anti-air vehicles made, not many countries had something remotely comparable, but it would not be long until the Germans had gained a particular interest in the vehicle which would play later on. The first prototype of the M42 Contraereo would be completed by January or February 1943, it would then also be presented for trials at the "Centro Studi Motorizzazione dell'esercito" (in English: "Center for motorization of the army").

In terms of mobility, the M42 kept pretty much all the previous stats of the M15/42 tank, meaning it could reach speeds of up to 40 km/h. When it came to survivability, it also kept the same protection values as the previous M15/42 tank it was based of, however it is good to note that the removal of the 2 x Breda 38 machine guns that previously would be installed in the hull, would instead be covered by a 42 mm armour plate. The new anti-air turret was for the most part exposed to incoming enemy fire, and did not offer adequate protection levels.

As development of this anti-air platform continued, it's likely that a handful of prototypes were made. What ceased the further development of the vehicle however was the 8th of September Armistice of Cassibile. During the confusion of leadership in Italy, the Germans would use that as an advantage to invade the north of Italy and set up a puppet state lead by Mussolini. Due to this, the Germans took over any production factories, any vehicle development and would integrate it into the German army. In this case, at least one unit of the M42 Contraereo was captured by the German army and was likely thoroughly examined by German engineers.

Description

GarageImage M42 (Italy).jpg


The Semovente M42 Contraereo (shortened as just M42 Contraereo, also nicknamed "Quadruplo"), is a Rank Italian self-propelled anti-aircraft gun with a battle rating of (AB), (RB), and (SB). It was introduced in Update 1.85 "Supersonic".

General info

Survivability and armour

The M42 Contraereo is based off the M15/42 hull with an opened top turret, surrounding the crew members. The gunner does have an exposed spot in the front, and if shown correctly to the enemy, can be machined gunned easily without them to have to fire their main cannon. The turret may protect you from small rifle caliber bullets, but 50. caliber and up, especially on the M4 Sherman will be able to penetrate your turret from anywhere, as it is generally weak against them. The hull armor is decent, still keeping the armor from the M15/42 hull, but don't expect to tank a lot of shots, as most of your enemies you will face at 3.3 will have better caliber weapons, with mostly encountering 75mm and Russian 76.2mm cannons. You may be able to bounce some smaller caliber shells like the 37mm cannons but don't rely on your hull armor as your turret will most likely be targeted by the enemy. You have a small crew count of 3 members, and with two in the turret, and having okay armor, you'll usually die in one hit.

Usage in battles

In Realistic battles, the Quadruplo is best used in the support role when tank hunting, sticking with teammates, assisting them and potentially distracting the enemy .Your best bet of killing any tank, usually a Sherman, Cromwell or T-34 is from the side as the APCR will pierce through their side armor, killing the tank. Light tanks such as M24s, Stuarts and Crusaders are able to be penetrated by the front, but usually this is only in close range engagements. T-50 and other slightly armored light tanks will be tougher to kill, but you're still able to flank them. You can kill basically any SPAA you see, as you'll usually encounter trucks or armored cars. Ambush and surprise tactics are good options to kill tanks effectively, as the enemy will stroll pass you, usually showing their side armor. Aggressive play styles are suggested to get the most out of the Quadruplo, similar when playing a Wirbelwind when tank hunting. Try not to expose yourself too much and move from cover to cover, as one hit from a tank shell, usually APHE will knock you out in one shot, or the machine guns pierce your turret armor and kill both your gunner and commander. When it comes to shooting down planes in the Quadruplo, it is best to get their attention so they try to strafe you, or surprise them as they come closer to you, when you have a good shot as they won't have enough reaction time to evade your shots if they connect. Be mindful that you are opened topped, and you'll less likely ti survive a strafe run. Despite the guns having a high fire rate, and being close together, the Quadruplo has a lower ammo count per gun with 12 with each gun, having a 48 in total loaded (essentially a discount Wirbelwind). It is easy to burn through it, so make sure you have a good shot on the aircraft you are trying to shoot down as you'll only have about 3-4 seconds of continuous fire before needing to reload.

Pros and cons

Pros:

  • PzGr 40 shells are great at penetrating tanks from the sides and knocking out modules
  • High mobility when spaded
  • Great armour for a SPAA
  • Guns have a very high rate of fire
  • Guns are placed very close together

Cons:

  • PzGr 40 is tier IV modification
  • Performance is inadequate when stock
  • Gap in the gunner's position of the turret armour
  • Turret can be penetrated by .50 cals heavy machine guns
  • High rate of fire makes it more difficult to adjust fire against planes
  • 3 crew members, all in turret
  • Low magazine count for the guns (12 ammo per cannon)

History

A prototype AA tank based on the M15/42 medium tank. The single prototype was captured by Germany upon Italy's surrender in September, 1943. Some sources have claimed it served as inspiration for the German Wirbelwind AA tank, which first saw service in mid-1944.
