Well, then there was the predecessor to the Mule, the HRP-1. 20 delivered between late 1947 and 1949, initially used by the Marine Corps (pay attention SASless) for developing vertical assault tactics, then passed on to the Coast Guard for SAR development. The remaining (attrition rate?) then went to the USN for dipping sonar and minesweeping development: talk about cutting edge!
OK, not US Army but still the lead in service machine to the H-25
