United States Army Air Defense Artillery School

The Air Defense Artillery School is the professional school of the Air Defense Artillery Branch of the US Army. It is at Fort Sill, Oklahoma. The school was organized as the 6th ADA Brigade until 18 May 2012, when it was redesignated as the 30th Air Defense Artillery Brigade. The decision to redesignate the 6th ADA to 30th ADA was made after Col. Bill Stacey, the then-6th ADA commander, discovered that the 6th ADA had no official ADA colors.

Current status
In June 2009, the Army Air Defense Artillery School and the 6th ADA Brigade relocated from Fort Bliss to Fort Sill. This move was a result of the 2005 BRAC moves. The motor transport operator (88M) course has moved to Fort Leonard Wood. There is a new Army policy replacing drill sergeants at AIT with regular noncommissioned officers from front line units. This is to free up drill sergeants for basic training. However, starting in 2018 Drill Sergeants made a comeback, somewhat due to 'disciplinary' issues amongst trainees.
