Soviet Anti-tank gun

The anti-tank gun of the USSR, more precisely an anti-tank rifle, was an easily-portable weapon designed to defeat armored vehicles. In development since 1936 across several design offices, it finally entered the field in the autumn of 1941, and along with it a new soldier's specialty – the anti-tank rifleman. These specially trained experts planned their shots carefully to disable their prey as swiftly as possible. In battle, the rifle was handled by one soldier, assisted by another. The weapon they bore could penetrate an armor thickness of 35 to 40 millimeters, at a distance of up to 300 meters.
The most famous feat of the anti-tank riflemen would be that of the 316th Infantry Division (later known as the 8th Guards), in the defense of Moscow in 1941. Under the command of Major General Ivan Panfilov, a group of anti-tank riflemen (consisting of 28 men with 11 guns) were able to destroy 18 of the enemy's 54 heavily armored vehicles.
