The United States Army Air Defense Artillery School is conducted 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 provoked when Col. Bill Stacey, the then-6th ADA commander, discovered that the 6th ADA had no official ADA colors.
