The first samples of the M10 arrived in the Soviet Union at the beginning of 1944.
On March 22, 1944 two self-propelled artillery regiments, the 1223^rd and the 1239^th were formed with 21 M10 each.
The 1239^th received its baptism of fire in July 1944 when fighting in the 16^th Tank Corps, 2^nd Tank Army, 1^st Belorussian Front.
After taking Lublin, the regiment moved out of Demblin/Poland to support the 1441^th self-propelled artillery regiment eqipped with SU-85 SPG advancing towards Aleksandrów.
On July 30, 1944, they came under attacks by the Luftwaffe, loosing several SU-85 on their march.
The M10s in contrast did not only suffer any losses at all but succeded to shoot down one JU-88 Luftwaffe bomber with the heavy Browning AA gun.
Later in August, with 17 guns, the the 1239^thself-propelled artillery regiment fought in the Warsaw area, where from 1 to 5 August 1944 they successfully repelled attacks of German tanks units.
According to regiment reports, 4^th battery alone knocked out 3 German tanks (including 2 "Panther"s) and 2 armored cars.

The 1223^rd self-propelled artillery regiment as part of the 29^th Tank Corps of the 5^th Guards Tank Army of the 3^rd Belorussian Front took part in the liberation of Belarus, the Baltic States and East Prussia in 1944/45.

Though the M10 "Wolverine" proved a highly successful antitank weapon that could compete successfully with even heavy German tanks at medium distances, further orders were abandoned in favor of the M4A2 76(W) "Sherman".
On May 1, 1945, 1223^rd self-propelled artillery regiment still had 10 M10, of which four were still fully serviceable.
