This involves a T-34 tank commanded by Gennady Aizenshtadt.
Gennady Aizenshtadt - "I had a young driver in my crew. The hatch would open when he drove. One time we were traveling and the tank was weaving from side to side like this. Someone was following us in a car and wanted to pass, but we kept getting in his way. My driver could not see what was happening behind him. He eventually got in front of us and stopped us. A captain or a major got out, drew his pistol . . . and killed him."
Interviewer "—The tank driver?"
Gennady Aizenshtadt - "Yes, the tank driver. There were two women and a young man in the car with him. I ordered my tank crew to open fire and killed them. When we arrived at our destination, I reported on the incident and did not suffer any repercussions."
