World War 1 machine gun

Answer 1

Stermgewehr. Also known as Mp44 and Stg-44. Browning 1919

No, no, no. The Sturmgewehr (aka Mp43 or Stg44) was the first assault rifle used in WW2. The Browning M1919 was not made until WW1 ended. Most of the machine guns used in WW1 were based on the Maxim design. They were heavy and cooled by water, but they would fire indefinitely as long as ammo and water were available. The Lewis machine gun used by the British was lighter and cooled by air. After WW1, water-cooled machine began to fade away slowly. The Browning M1919 was basically the same machine gun used in WW1 but converted to air cooling instead of water.
