The M10 tank destroyer was an American tank destroyer of World War II. After US entry into World War II and the formation of the Tank Destroyer Force, a suitable vehicle was needed to equip the new battalions.
 
Approximately 52 M10s were supplied to the Soviet Union through Lend-Lease. They were used to form two self-propelled artillery regiments (SPA) The first was the 1223rd Self-propelled Artillery Regiment of the 29th Tank Corps, part of the 5th Guards Tank Army.

The 1239th Self-propelled Artillery Regiment was part of the 16th Tank Corps, 2nd Tank Army. It fought in Belorussia and Poland in 1944.
