Captured by Finns in summer of 1944, two of them in operational condition (we smoked lots more.. but those usually exploded..) but this one was stuck on a swamp.. today its in Parolas armored museum in its original Soviet markings..

Nice beast btw.. and was converted to armored recovery vehicle.. (the another captured vehicle was not, and was used and lost in battle.. day or two after its capture..) but has now been returned to its orginal condition.. (when it was armored recovery vehicle, it had its gun removed etc..)

Also note the T-34/85 (and between it and JSU-152 theres KV..) in Finnish markings, we had many of those and 76mm versions and used them alot in combat, in fact they were our best tanks that reached the front at any stage of ww2..
