The 66th Military Intelligence Brigade ("Six-Six-M-I") is a United States Army brigade, subordinate to United States Army Intelligence and Security Command and based at Wiesbaden Army Airfield, Wiesbaden, Germany. After years of history as a counter intelligence/intelligence group with headquarters in Munich and geographically dispersed detachments, it became a brigade on 16 October 1986, but was inactivated in July 1995. Reformed again as an intelligence group in 2002, it became a brigade again in 2008.
