Machine guns changed the face of warfare. They industrialized the way wars were fought. They were among the most used weapons during World War I and World War II. With dozens of designs and variations that the US had made, safe to say that the United States was a fan. Here are some of the most awesome ones:

Browning M1917

Patented by John Moses Browning in the 1900s, his heavy(at that time) machine gun was used by the United States during World War I, World War II, Korean War, and Vietnam War. It was heavy enough that four people needed to man it. It could fire up between 400 to 600 rounds per minute. You could also rely on it as it was once tested, and it fired 20,000 rounds without a miss. Its ammunition box was first made of wood until it was replaced with an expendable metal box during WWII. More often, it was mounted on vehicles like a jeep. The early version had a water jacket around the barrel to keep it cool and maintain a high rate of fire.  In WWII the infantry tended to favor a shrouded barrel because it was less of a beast to lug around but at a reduced rate of fire.

A popular one, Browning Automatic Rifle (BAR), was designed to be carried by the soldiers with a sling over the shoulder. This light machine gun fired .30-06 rounds at nearly 2,700 ft. per second. That capability is enough to pierce a light tank during WWI. According to Britannica, “It can fire up to 650 rounds per minute but can also fire single shots or bursts of two or three to increase accuracy.” By the end of the war, there were approximately 52,000 BARs delivered. In 2015, a 94-year-old BAR was found by a US Army, and guess what? It’s still functioned perfectly. In infantry squads, there was always a BAR man whose job was fire suppression and the BAR was actually ideal for the role.  The impact of the rounds was devastating to most cover and it was far more mobile than the German MG32 light machine gun.

Also called Tommy Gun and Trench Broom, this gun was designed for combat in the trench during World War I. Tommy Gun was the first machine gun designed around a pistol caliber. Because of its high rate of fire at 1,200 rounds per minute, it was issued more frequently to scouts, commissioned and non-commissioned officers, and other soldiers tasked to raid. It was perfect for close street fighting but was ineffective in heavy jungle cover. It was also a beast to lug around.  It weighed more than than the M1 Garrand did.
