The 45mm anti-tank gun, M1942, was designed to provide a weapon with greater penetrative power. However, like the prior M1937, it was outdated against the modern UN armour. The light-weight gun is mounted on the modified carriage of the M1937 anti-tank gun. The M1942 has a slender whip-like tube that is three inches longer than the tube of the M1937. The gun was relatively lightweight and of considerable value to KPA infantry.
