Russian servicemen demonstrated the launch of a 3D6 smoke munition from the 902 "Tucha" system from a T-80BVM tank; the 81-mm smoke munition is part of the standard equipment. But in this case, the launcher has been rearranged. It is assumed that the tank, having approached the enemy closely, will be able to smoke the enemy trenches, which will force him to retreat or will interfere with firing at the tank. Smoke munitions are fired at a distance of 10 to 350 meters, after falling to the ground they emit dark smoke. The smoke screen lasts up to 1.5 minutes, its length reaches 30 meters and the height up to 10 meters, depending on the wind and air temperature.
