Headquarters Command, Fort Polk
"Warrior Brigade"
"Devil Troop Brigade"
"Freedom's Guardian"

In late 2005, the garrison command structure at Fort Polk, Louisiana was reorganized and the Headquarters Command inactivated and replaced with US Army Garrison, Fort Polk, an element of Installation Management Command. The 83rd Chemical Battalion and 46th Engineer Battalion were subsequently reassigned to the 1st Combat Support Brigade. The 142nd Corps Support Battalion was reassigned to the 15th Sustainment Brigade. Administrative control of the 115th Field Hospital passed directly to the Joint Readiness Training Center, though the unit remained under the operational control of the 1st Medical Group at Fort Hood, Texas. The Fort Polk NCO Academy subsequently became the JRTC NCO Academy and was eventually relocated to Fort Sill, Oklahoma. The 5th Personnel Service Battalion was subsequently inactivated.

The Headquarters Command, Fort Polk, also known as the "Warrior Brigade," ensured the combat readiness of assigned Modification Table of Organization and Equipment (MTOE) units and prepared them to support FORSCOM/Theater commander-in-chiefs (CINCs) for wartime or contingency deployments. It also provided command and control, training validation, Uniform Code of Military Justice (UCMJ), administrative, and logistical support to Reserve Component units mobilized at Fort Polk and provided support to the Joint Readiness Training Center (JRTC) and Fort Polk.

The Warrior Brigade evolved to meet US Forces Command's readiness mission and provides support to the JRTC. They were "Freedom's Guardian." Warrior Brigade soldiers had participated in many major training deployments and combat operations in recent years. They had served in such places as Southwest Asia, Honduras, Cuba, Somalia, Suriname, Bosnia and Haiti. They had also participated in virtually every JRTC rotation since the center moved to Fort Polk in 1993.

The Headquarters Command, Fort Polk was first constituted in July of 1962 as Headquarters, Special Troops assigned to Fort Polk, Louisiana. It was redesignated on 1 July 1970 to Headquarters, Garrison Troop Command, Fort Polk, Louisiana and again on 25 February of 1971 to Headquarters Command, Fort Polk, Louisiana.

In March 1982, the unit was granted approval to use the name "Devil Troop Brigade" reflecting the unit's support mission to the 5th Infantry Division (Mechanized). Major subordinate commands of the Devil Troop Brigade were: 588th Engineer Battalion and assigned units; 15th Evacuation Hospital and assigned units; Provisional Battalion and assigned units; 5th Personnel Service Company; 36th Medical Detachment; and 5th Infantry Division Noncommissioned Officer Academy.

During Operation Desert Storm, the Command's normal authorized strength was more than doubled. Seven battalions and 13 separate companies from the Active Army, Army Reserve, and Army National Guard were assigned for command, control, training, validation and deployment. Simultaneously, the Command deployed 2 of its organic battalions and 7 of its organic companies and detachments to Southwest Asia. In all, more than 8,000 soldiers from 32 units deployed via the Command to Southwest Asia.

On 30 June 1993, the Command was granted approval to use the name "Warrior Brigade" reflecting the unit's support mission to the Joint Readiness Training Center.
