Marines used the M1917 and M1919 .30 cal Brownings, the M2 .50 cal Browning, the BAR Browning automatic rifle (Browning was one of the major saints of projected forces), but none had such high rates of fire. I think the German MG42 was one fo the few that did. An odd weapon used briefly by the Marines was the Johnson rifle, and they stole M1 Garands from the army until they got their own.
