The "Valentine" Medium Tank in the USSR
Soviet Union received 2394 tanks from UK and 1388 from Canada. It was the most popular British tank among Soviet tankers. What concerns its reliability and durability lets refer to one example: at the beginning of Melitopol Operation (October 24, 1943) the 19th Tank Corps had 101 T-34/76 and 63 Valentine tanks. During a battles Corps lost 78 of T-34's and 17 Valentines tanks and all tanks were used with identical intensity.
