Yet another tank was recently extracted from one of the lakes near St. Petersburg. There are plenty of tanks left since WW2, each year a few of them are being pulled out by different enthusiasts. This one is particular by it’s model “BT” which was translated as “Quick Moving Tank”. It had very narrow tracks so it had to move only on good roads, and the tracks could be completely removed so that it could roll on the rubber coated inner wheels on the good surfaces when army had to relocate quickly and there were good roads available.
