| Notes | The 45mm 53-K anti-tank gun was derived from the 37mm 1-K, and was rechambered to fire the larger round. It was an adequate weapon for the period and could knock out the early models of panzer, but once the Germans started to up-armour their tanks, the gun was found inadequate. It was issued to anti-tank units at battalion and divisional level, with others issued to independent anti-tank regiments. |
