Tank cannons
The BK90 is a German modification of the American 90 mm gun M1/M2/M3 taken from old M47s. It has access to HEATFS, HE, and HESH which is the only new round.
The gun's HEATFS shell has amazing penetration at long range for the BR combined with a short reload time. The gun its great for ambushing and sniping, however lacking kinetic energy projectiles makes even trees an obstacle.

The BK90 with HEATFS is a formidable opponent on the battlefield that can penetrate every 6.7 tank's frontal armour at any range. It is best used in hit-n-run types of attack due to the vehicles it is mounted on.
