With 2 Machine-gun sections & and Command Carbine Team
The Browning water-cooled Model 1917 was originally designed for use during the First World War, the M1917 continued to see use in World War II. The Americans used a variety of automatic weapons in the years before WWI including Maxims, Colt 95 ’Potato Diggers" and Benet-Mercies. During the war they also acquired Vickers, and French Chauchats (which some considered the worst machine-gun ever made).
In the mean time independent gun designer John Browning had also been working on some different ideas for automatic weapons, included a gas-operated weapon for Colt. Re-evaluating the Maxim recoil operated design he set to work designing a similar weapon for use by the US Army. Initially the ordinance department ignored his design but finally in 1917 he was asked to demonstrate his machine-gun. This first test was successful and after war was declared in 1917 he was asked again to further test his weapon.
At the tests he fired 20,000 rounds through Browning Machine-gun, and then
to show it was no fluke he fired a further 20,000 rounds with no jams or other
mishaps. The inspecting board still were uncertain whether this performance
could be maintained in a production model. Browning then produced a second
weapon, which he
fired for 48 minutes 12 seconds before stopping, Browning then stripped and
reassembled the weapon while
blindfolded. The M1917 was adopted by the US Army in 1918 and continued to be
used until the end of WWII.
