The 172nd Attack Squadron (172 ATKS) is a unit of the Michigan Air National Guard 110th Wing located at Battle Creek Air National Guard Base, Battle Creek, Michigan. The 172nd is equipped with the MQ-9 Reaper drone.
The squadron was first organized during World War II as the 375th Fighter Squadron. It saw combat in the European Theater of Operations as an element of VII Fighter Command before returning to the United States, where it was inactivated.
In May 1946, the squadron was allotted to the National Guard as the 172nd Fighter Squadron. During the Korean War, the squadron was called into federal service and acted in an air defense role until being returned to the Michigan Air National Guard in 1952. It had various flying missions, including fighter, reconnaissance and airlift until 2013, when it was converted to a support unit.
