This is coolbert:
"designed to replace four different shells; the current multipurpose (bunkers and light armored vehicles) M830A1 (and its improved version M908), the HEAT (shaped charge anti-tank) shell, and the M1028 ('shotgun' shell) rounds."
From the Internet web site Strategy Page and thanks to same.
"November 26, 2021: After 15 years of development, the U.S. Army’s new XM-AMP (Advanced Multi-Purpose) 120mm tank round was considered stable enough in 2020 to be test fired by troops."
One multi-purpose tank round to replace the multiplicity of dedicated purpose types of rounds as might be carried in a modern battle tank. Project five YEARS behind schedule and not yet ready to become part of the standard inventory.
THE U.S. military tank [current version] main gun to be replace by a much more advanced 120 mm caliber gun?
ONE HIGHLY ADVANCED, MULTI-PURPOSE AND PROGRAMMABLE SHELL WILL NOW REPLACE THEM ALL?
A worthy concept but I hope this is not going to be an instance of "trying to do it all but not being able to do any of it."
