Field gun elevates from minus 6 degrees to positive 16.5 degrees and fires HE, HEAT, APDS and APCBC ammunition to 10,000 yards.
When I was using the AT gun I only had AP as an ammo choice.and yes I do agree, if the trajectory was supposed to be similar to the firefly then there is a serious problem somewhere.the firefly shoots an almost flat trajectory and the new AT gun shoots a very arched trajectory
