Yea, the insignia (again :P) is wrong, but the vehicle is not.
During the fighting in summer 1944 we captured two ISU-152 assault guns, other was badly damaged and sent back to rear for repairs, but another was pushed immediatly in service against its former owners, even thou it was lost 6 days later.
The repaired unit was converted into armored recovery vehicle after the war, but was converted back to its orginal outfit at the 1960s and put into display at the armored museum in parola.
