Ukrainian M1 Abrams tanks have been enhanced with ARAT protection. Ukrainian M1A1SA Abrams tanks, American-made, began to be equipped, presumably, with ARAT (Abrams Reactive Armor Tiles) dynamic protection of the first generation. ARAT dynamic protection was developed in 2004, specifically for the M1A1 and M1A2 Abrams tanks. The BRAT (Bradley Reactive Armor Tiles) dynamic protection system, previously developed for the Bradly infantry fighting vehicle, was taken as the basis. The first generation of ARAT-1 protection consists of modules designated as M19. ERA units are installed on the aprons of the tank hull; there is none in other places. The modules protect the tank from drones, but cannot protect against the Kornet ATGM and other systems.
