Many of the 1917s were given to South Vietnam. The last ones in regular US service were on the machine gun infiltration course at Fort Benning, Georgia, where their sustained-fire capability was an advantage in long nights of shooting over the heads of low-crawling trainees. The gun did continue to see service in some Third World armies well into the latter half of the 20th century. Some are still in use today by irregular military forces because the water cooled barrel allows for long periods of sustained fire.
