The 533rd Military Intelligence Battalion (MI BN) was constituted on 1 June 1946 in the Regular Army as the 533rd Counter Intelligence Corps Detachment. Activated in Germany, the battalion has served in various intelligence roles, providing support during the Cold War and later in Korea. Over the years, the unit has conducted human intelligence, signals intelligence, and counterintelligence operations to support U.S. Army and allied missions. Today, the 533rd MI BN operates as part of the 501st Military Intelligence Brigade, stationed in South Korea, where it continues its critical role in intelligence collection and analysis on the Korean Peninsula.
