ヴィッカース重機関銃
By the early 1900s, the U.S. military had a mixed collection of automatic machine guns in use that included M1895 "potato diggers", 287 M1904 Maxims, 670 M1909 Benét–Mercié guns, and 353 Lewis machine guns. In 1913, the U.S. began to search for a superior automatic weapon. One of the weapons considered was the British Vickers machine gun.
