Combat Shotguns of the US Military
The United States was the first country to formally issue a modern combat shotgun. Innovations by John Browning made it possible for repeating & self-loading shotguns to become reliable weapons suited for war. Thanks to this head start in shotgun development the US adopted various “trench guns” to be used for close quarters combat, which can identified by their heat shield & bayonet lug. These trench shotguns were so effective that the Germans protested their use as a war crime and threatened to execute any prisoners caught with shotgun shells. The 12 gauge was adopted as the preferred bore diameter for shotguns in US service and become the de-facto global standard for the next century. The US Military continues their tradition to the present, maintaining the world’s largest arsenal of modern shotguns.
