505th Military Intelligence Brigade
The 505th Military Intelligence Brigade (Theater) is a military formation of the United States Army falling under the command of United States Army North. History 
The 505th Military Intelligence Brigade traces its history back to 30 January 1951 when the 505th Communication Reconnaissance Group was constituted within the Organized Reserve Corps (predecessor to the Army Reserve). On 19 February 1951, the group was activated with its headquarters in Boston, Massachusetts. On 9 July 1952, the Organized Reserve Corps was re-designated as the Army Reserve and the group consequently joined. On 10 September 1956, the group was re-designated as the 505th Army Security Agency Group. However, on 1 July 1959, the group was inactivated. On 15 February 1963, the group was re-activated with its headquarters in Boston, Massachusetts. However, on 31 January 1968, the group was inactivated once again. On 1 February 1990 the group became the 505th Military Intelligence Group, and on 8 August 1995 the headquarters became the headquarters and headquarters detachment. Under the re-organization of the Army following the end of the Cold War, the group was re-activated as the 505th Military Intelligence Group (East) with its headquarters at Fort Gillem, Georgia on 18 February 1998. At this time, the group had two technical intelligence (TECHINT) companies at Fort Devens in Massachusetts, an imagery analysis battalion on Staten Island, New York, and an exploitation company in Orlando, Florida. On 23 September 2015, the group was re-activated as 505th Military Intelligence Brigade (Theater) as part of United States Army North. The group's headquarters were established at Fort Sam Houston in Texas, part of Joint Base San Antonio. The brigade was the first of its kind, becoming the only Army Reserve-led theater military intelligence brigade. At the time of the brigade's reformation, it had a strength of 600 active duty, reserve, and Army National Guard soldiers, and only the seventh brigade of its type within the Army. In late 2018, the brigade headquarters and headquarters company were deployed to the Mexico–United States border by order of President Donald Trump to counter the illegal migrant caravans moving from Mexico. Nickname: "Victory Brigade"
