|This page is about the Italian SPAA M42 Contraereo. For other usages, see M42 (Disambiguation).|
The Semovente M42 Contraereo (shortened as just M42 Contraereo, also nicknamed "Quadruplo") is a rank II Italian self-propelled anti-aircraft gun with a battle rating of 3.3 (AB/RB/SB). It was introduced in Update 1.85 "Supersonic".
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 to the enemy, can be machine-gunned easily without them to have to fire their main cannon. The turret may protect you from small rifle-calibre bullets, but .50 calibre 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 armour is decent, still keeping the armour from the M15/42 hull, but don't expect to tank a lot of shots, as most of your enemies will have better calibre weapons, mostly encountering 75 mm and Russian 76.2 mm cannons. You may be able to bounce some smaller calibre shells like the 37 mm cannons but don't rely on your hull armour 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 armour, 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 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 play styles 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 belt with 12 in each gun, having 48 loaded in total at any time (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
- 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
- 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
- 2 of 3 crew members crammed inside the turret
- Low magazine count for the guns (12 rounds per belt)
- Hull rocks back and forth when firing causing some rounds to miss
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.
