World War 2 was a continuation of the fighting of World War 1 and relied on both old and new infantry-level weapons as a result.
Despite the advances made in other areas of warfare by the time of World War 2 (1939-1945), it still fell to the tactics, equipment and bravery of the individual infantryman to claim the victory. Brutal house-to-house was the norm when wide-open fields and country sides were not available. As a result, the warfighter had to equipped with various weapons to see the mission through and this went on to include pistols, submachine guns, machine guns, shotguns, grenades and support weapons. By the end of the years-long bloody conflict, the infantryman had evolved to become a new, more flexible and deadly fighting component than those of war's past.
