Special Troops Battalion, 3rd Brigade Combat Team
The mission of the Special Troops Battalion, 3rd Brigade Combat Team, "Gladiators," is to, on order, deploy and conduct ISR operations, security operations, and operate tactical networks to enable 3rd Brigade Combat Team to conduct full spectrum operations. It would then, on order, redeploy and prepare for future combat operations. By providing intelligence, signal, military police, and Nuclear-Biological-Chemical (NBC) reconnaissance capabilities at a brigade level, the Special Troops Battalion, 3rd Brigade Combat Team plays a valuable role supporting the 3rd Brigade, 1st Cavalry Division.
The Special Troops Battalion, 3rd Brigade Combat Team was first constituted on 20 August 1921 in the Regular Army as Headquarters Troop, 3rd Cavalry Brigade, and assigned to the 2nd Cavalry Division. The unit was activated on 21 February 1941 at Fort Riley, Kansas.
The unit was relieved on 15 July 1942 from assignment to the 2nd Cavalry Division and concurrently converted and redesignated as Headquarters Company, 9th Armored Division Trains. It served in three campaigns of the Second World War with the 9th Armored Division: Rhineland, Ardennes-Alsace, and Central Europe. At the end of the Second World War the unit was inactivated on 13 October 1945 at Camp Patrick Henry, Virginia.
The unit was relieved on 15 July 1963 from assignment to the 9th Armored Division and concurrently converted and redesignated as Headquarters Company, 3rd Brigade, 1st Cavalry Division. The unit was activated on 1 September 1963 in Korea. The unit moved to Fort Benning, Georgia in 1965 as part of the reflagging of the 11th Air Assault Division (Test) as the 1st Cavalry Division (Airmobile). Following the reflagging, the 1st Cavalry Division departed for Vietnam. The unit participated in 16 campaigns of the Vietnam conflict with the 3rd Brigade, 1st Cavalry Division: Defense, Counteroffensive, Counteroffensive Phase II, Counteroffensive Phase III, Tet Counteroffensive, Counteroffensive Phase IV, Counteroffensive Phase V, Counteroffensive Phase VI, Tet 69/Counteroffensive, Summer-Fall 1969, Winter-Spring 1970, Sanctuary Counteroffensive, Counteroffensive Phase VII, Consolidation I, Consolidation II, and Cease-Fire.
After Vietnam, the unit returned to Fort Hood, Texas, where it was inactivated on 15 September 1980. The unit was reactivated on 21 May 1991 at Fort Hood, Texas.
As part of the transformation of the 1st Cavalry Division to the US Army's new modular force structure, the unit was reorganized and redesignated on 17 October 2005 as Special Troops Battalion, 3rd Brigade Combat Team, 1st Cavalry Division. This unit integrated assets that had previously been held at division level, but habitually assigned to the 3rd Brigade. Under the modular transformation these assets became organic to the reorganized and redesignated 3rd Brigade Combat Team, 1st Cavalry Division.
The Headquarters and Headquarters Company was composed to personnel that had reflagged from the 8th Engineer Battalion, while its A and B Companies came from similarly reflagged companies of the 312th Military Intelligence Battalion and 13th Signal Battalion Respectively. The military police platoon and NBC reconnaissance platoon absorbed personnel which had previously been assigned to the 68th Chemical Company and the 545th Military Police Company. The Brigade Special Troops Battalion, 3rd Brigade Combat Team had a total of 56 different military occupational specialties and equipment ranging from Tactical Unmanned Aerial Vehicles to M2A3 Bradley Fighting Vehicles making it a truly unique unit.
