What weapons did a soldier carry in World War 2?

That depended on which army they were in. The infantrymen of Britain and Canada mostly carried the Lee-Enfield 0.303 rifle. The American Army mostly carried the the M1903 Springfield 30.06 or the M1 Garand Carbine. The Germans usually carried the Mauser Karabiner 98K. -Other troops of all armies carried more 'role specific' weapons such as sub-machine guns, light machine guns and pistols.
