1st Maneuver Enhancement Brigade
1st Combat Support Brigade (Maneuver Enhancement)

The mission of the 1st Maneuver Enhancement Brigade is to, on order, conduct mobility, protection, and stability or civil support operations in an assigned area of responsibility to preserve freedom of action of the supported force. The maneuver enhancement brigade was designed as a command and control headquarters with a robust multi-functional brigade staff that was optimized to conduct maneuver support operations. Maneuver support operations integrated the complementary and reinforcing capabilities of key protection, movement and maneuver, and sustainment functions, tasks, and systems to enhance freedom of action.

The 1st Maneuver Enhancement Brigade was first constituted on 3 January 2006 in the Regular Army as Headquarters and Headquarters Company, 1st Combat Support Brigade and activated on 16 September 2007 at Fort Polk, Louisiana. There it replaced the Headquarters Command, Fort Polk, also known as the "Warrior Brigade," as a multi-functional command element controlling various elements operating in support of the Joint Readiness Training Center (JRTC) and Fort Polk.

In 2007, the 48th Chemical Brigade was activated, which took control of the 83rd Chemical Battalion. The 83rd Chemical Battalion continued to provide support for the JRTC and Fort Polk via the 1st Combat Support Brigade. The unit was redesignated on 1 February 2008 as Headquarters and Headquarters Company, 1st Maneuver Enhancement Brigade.
