HEAT/MPAT Tank rounds will be obsolete in 2042
So just wanted to throw it out there that by 2042 tanks won't be running dedicated Mpat or Heat rounds. By then Abrams will be using:
"The XM-1147 Advanced Multi-Purpose (AMP) round, a line-of-sight tank round developed by Northrop Grumman Defense Systems for the Abrams tank, is designed to do the job of four existing rounds, consolidating their abilities into one munition.
It will replace the M830 High Explosive Anti-Tank (HEAT) and the M830A1 Multi-Purpose Anti-Tank (MPAT), both designed for light armor targets and aerial targets, in the case of the MPAT; the M1028 canister (CAN) round, used to hit infantry targets outside the range of machine guns; and the M908 obstacle reducing (OR) round, according to the Army release."

It's basically one round that can be programmed to produce the effect of any of those four rounds. So in game tanks should be able to switch target types on the main gun ammo the same way soldiers can switch between standard, high power, CQB and AP rounds on the fly.
