M60

The M60 machine gun is a machinegun firing 7.62×51mm NATO cartridges from a disintegrating belt of M13 links, with some variant also sports a portable lightweight bipod.

It first entered service during the Second World War, with the Allies using it extensively for Ranger and APC, making them very effective against infantry.

In Red Alert Universe, the M60 is continued use by GI during Third World War and it repeat with clearly superior both in range and firepower from (presumably) PPSH-45 wielded by Conscript, and probably costlier too. The recoil however was so great that the M60 could only be fired when on a bipod, forcing GIs to use a submachine gun while mobile.
