How the U.S. Army Will Attack the Next War: New Tanks and New Ammo

The Army is now engineering a new Advanced Multi-Purpose 120mm ammunition round for a far-superior M1A2 SEP v4 Abrams tank variant for the 2020s and beyond –designed to be more lethal, faster, lighter weight, better protected, equipped with new sensors and armed with upgraded, more effective weapons, service officials said.

The new ammunition will replace four different kinds of ammunition with a single round.

The AMP round will replace four tank rounds now in use. The first two are the M830, High Explosive Anti-Tank, or HEAT, round and the M830A1, Multi-Purpose Anti -Tank, or MPAT, round.

The latter round was introduced in 1993 to engage and defeat enemy helicopters, specifically the Russian Hind helicopter, Army developers explained. The MPAT round has a two-position fuse, ground and air, that must be manually set, an Army statement said.
