General Information Edit
A machine gun is a firearm designed to fire bullets as long as the trigger is held, as opposed to semi-automatic weapons that require a trigger-pull for each bullet. The first truly automatic machine gun, the water-cooled Maxim, saw action in WWI, helping make that conflict the high-casualty nightmare it would become.
A Heavy Machine Gun in history is usually a machine that fires larger caliber rounds than a standard MG. HMGs were not portable devices and were often only mounted in defensive emplacements, tanks, and rarely on aircraft.
