The T-44 was issued to three tank brigades mustered on 15 September 1944 for training purposes, but these formations (6th Guards, 33rd Guards, and 63rd Guards Tank Brigades[REF]) were re-equipped with T-34-85 tanks prior to entering the Battle of Berlin and Prague Offensive.
In 1961, a number of T-44As were modernized with parts from the T-54 main battle tank and other upgrades and received the designation T-44M.
