According to information and pictures published on the Twitter account of “RonKainen” on November 9, 2022, hundreds of retired US Marines M1A1 Abrams Main Battle Tanks (MBTs) were sent from Sierra Army Depot to Anniston U.S. Army Depot to be rebuilt and upgraded to the M1A2 SEP V3 version for future delivery to U.S. Army.
As of 2020, the Marine Corps has been pursuing a force restructuring plan named Force 2030. Under this directive, all US Marine tank battalions were deactivated and its M1A1 tanks were transferred to the Army by the end of 2021.
The U.S. Marine Corps has planned to eventually divest the entirety of its M1 fleet, more than 400 vehicles in total, as part of the new Force Design 2030 plans.
The M1 Abrams was followed by the M1A1, with the first production example being completed in August 1985 and continued until early 1993. General Dynamics Land Systems began delivering the first of 299 FY90 M1A1 MBTs in April 1991.
