The Academy of Military Science (AMS) was an 8-week (formerly 6 as of March 2014) officer commissioning program of the United States Air Force.
[1] AMS was originally located at McGhee Tyson Air National Guard Base, outside Knoxville, Tennessee.
The move was initiated by a question in 2006 from the Chief of Staff of the Air Force about the potential of a "shared common experience" at a single location among active duty, Guard and Reserve officer candidates.
The primary reason for AMS being a six-week course instead of the traditional OTS nine-week course was that, on average, 85 percent of Air National Guard members have had prior military service when they arrived at the AMS course, versus about 40 percent of OTS students having had the prior experience.
[2] Air National Guard personnel serving on the staff come to OTS under a "Title 10" (federal) assignment that precludes them from having to leave Maxwell AFB for state service.
