Warren emailed me and said " The photo shows the events of 21 August 1968 in the town of Liberec.
This is not intentional T-62, but rather resulted from the fact that the local population tried to somehow prevent * "Soviet invasion" and you can probably treat it as a "work accident" T-62 (in terms of collisions). Although the term "accident" is not quite appropriate here. Under the rubble killed two people and several injured. In Liberec killed a total of 9 people. Many of them are victims of fire with machine guns"
