Polish forces in exile after the fall of Poland were reequipped by their allies. Polish LWP forces fighting alongside the Red Army were equipped with T-34, T-70 and IS-2 tanks, along with ISU-122 and SU-76 self-propelled guns. Polish forces in the west were equipped out of British stocks including M3 and M5 Stuarts, M4 Shermans and a small number of Cromwells. Polish armor units were participants in the Battle of Berlin and played an important role in the campaign in Normandy.
