Maybe it is the first time you see real "alive" tanks and infantry combat vehicles instead of museum exhibits painted green. While operation they sound like a jet. In fact this is how a gas-turbine engine works. When they start shooting it seems you go deaf.
These are the pictures of the night tank playwar of Kantemirovskaya tank division under Naro-Fominsk town.
T-80 tank — the main battle tank produced in the USSR. The first production tank with a single gas-turbine power plant. In the inventory of the USSR's army since 1976.
The tank fires very very plunk.
