The browning m1919 was developed originally as adaptation of the browning m1917 as an air-cooled closed-bolt belt-fed medium machine gun, by John M Browning. It served as the main general-purpose machine gun of the United States military, as it was chambered to fire .30-06 cartridge, but due to the lend-lense act was signed, many m1919s were re-chambered in the standard rifle cartridges of other nations' military that were allied to the U.S. during World War II, to serve as their own machine guns, an famous example of the .303 browning serving as the main aircraft armaments of the Supermarine Spitfire and Hawker Hurricane fighters, as well as other countries with their own sufficient industrial base to mass-producing their own m1919s (i.e. FN Herstal of Belgium).
The Browning M1919 is usually mounted as the fixed armaments or movable turrets of any militaryaircrafts, and ground vehicles, as well as it being held and fired by the user's hip or on a tripod, as its infantry role needed it to be.
