The AMX-13 Défense Contre Avions (DCA) canon de 40 mm is the fourth variant of the AMX-13 light tank family. Due to a scarcity of self-propelled anti-air (SPAA) vehicles in France following World War II, attempts were undertaken in the 1950s to repurpose existing tank chassis for anti-air tasks. The main weapon of the prototype is a 40 mm Mle51 T1 cannon based on the 40 mm Bofors L/70 cannon. The resulting vehicle is called the AMX-13 Défense Contre Avions (DCA) canon de 40 mm, and it is comprised of an AMX-13/75 FL10 chassis with a rear-mounted armoured SAMM S-980 turret that allows firing at 90° elevation. With its sloped sides and full 360° traverse, the turret provided adequate overall protection.

Introduced in Update 1.75 "La Résistance", the AMX-13 DCA canon de 40 mm is extremely versatile, as it can effectively execute both anti-air and anti-tank duties. It possesses an autocannon with a decent firing rate and accuracy that can easily knock down enemy aircraft. This, combined with the deadly firepower it has access to, makes it an extremely dangerous vehicle. Furthermore, its mobility can be used to flank across the battlefields and engage poorly armoured vehicles in the enemy team early in the battle. Its interchangeable ammunition belts enable this vehicle to quickly convert between different types of ammunition. This vehicle is a tremendous beast in the right hands, easily capable of destroying many tanks in battle.
