Modernization Programs
Modernization programs, such as Tank Urban Survival Kit (TUSK), remain in place constantly, so M1 Abrams stay pertinent on contemporary battlegrounds. The M1 Abrams tank received armor upgrades and a gun shield with TUSK, which added defense in the rear and side. The purpose was to improve the M1 Abram’s fighting ability in urban environments. The kits are field-installable, which means the vehicles do not have to be recalled to a maintenance depot.
