Chief Master Sgt. James Clemenson gives his grandson a hug June 4, during his retirement ceremony at the North Dakota Air National Guard, Fargo, N.D. Clemenson is the last enlisted Airman to have been stationed in Vietnam to retire from the Air Force. Clemenson did two tours in Vietnam with the U.S. Army from October 1970 through April 1972. He joined the North Dakota Air National Guard in 1973 and has most recently served as the National Guard Bureau senior enlisted manager for the joint staff, Washington, D.C. He has served in the United States military for 41 years. Only one other active Airman, Chief Master Sgt. Jim Honeycutt, still remains in service that wears a Vietnam Service Ribbon, although it's for temporary duty in country versus a mobilization. Clemenson and Honeycutt's status is among active-duty Airmen and does not include drill status Guardsmen, on which no clear statistics were available.
