The Browning M1919 is a .30 caliber medium machine gun family widely used during the 20th century. It was used as a light infantry, coaxial, mounted, aircraft, and anti-aircraft machine gun by the U.S. and many other countries, especially during World War II, the Korean War, and the Vietnam War. Although it began to be superseded by newer designs in the later half of the century (such as by the M60 machine gun), it remained in use in many North Atlantic Treaty Organization (NATO) countries and elsewhere for much longer. It is very similar in design to the larger .50-caliber M2 Machine Gun, which is also a Browning-designed weapon and is still in NATO service.

A field gun is an artillery piece. Originally the term referred to smaller guns that could accompany a field army on the march and when in combat could be moved about the battlefield in response to changing circumstances. This was as opposed to siege cannon or mortars which were too large to be moved quickly, and would be used only in a prolonged siege.

The M1 Garand (officially the United States Rifle, Caliber .30, M1) was the first semi-automatic rifle to be generally issued to the infantry of any nation. In 1936, it officially replaced the bolt-action M1903 Springfield as the standard service rifle of the United States Armed Forces and was subsequently replaced by the selective-fire M14 in 1957. However, the M1 continued to be used in large numbers until 1963 and to a lesser degree until 1966.
