The AEC Armoured Cars were a series of vehicles developed during World War 2. After the British experience against Italian armoured cars in the Western Sahara, AEC decided to develop their own vehicle while the Daimler Armoured Car was still in development. A total of 629 units were built and entered service in 1941. Early versions tried to have the same firepower and armour as other British cruiser tanks but they failed. The Mk.II version used a larger turret for a three-man crew with a 6-pounder gun, redesigned front hull, and a 158 hp (118 kW) diesel engine.

It was introduced during Update 1.75 "La Résistance" in the 2017 "Festive Quest" that took place between 22 December 2017 to 22 January 2018. The AEC Mk II is similar to the AEC AA, with a different turret housing a 57 mm 6-pounder cannon rather than two synchronized Oerlikon 20 mm anti-aircraft cannons. As such, the vehicle has a lower profile than its predecessor, which grants it more stealth capabilities. In addition, there is a 7.62 mm BESA machine gun for use, which is nice for dealing with lightly armoured targets such as open-topped anti-aircraft vehicles and SPGs.
