The protoype of this tank is A15 Cruasder cruiser tank of British Army during World WarII.Compared with the A15,its body and turret are enlarged enough to carry a larger caliber gun and other modern weapon systems.At the same time,it has smaller projection area and better bullet avoidance to enhance its survivability,including the use of hollow armor to resist the impact of hollow charge armor piercing projectiles.Of course it inherits the excellent mobility of the original Crusader tank,andis even more agile.It can easily reach 70 mph on flat ground and 50 mph on cross-country,enough to chase most ground targets. What is more,I also gave it ability to sail on the water,so it is a real cruiser now!Turn on group 1,the A15II will be able to run on the water with a jet engine. I hope you will like this LMBT,thank you!
