1st Maneuver Enhancement Brigade

The 1st Maneuver Enhancement Brigade (1st MEB) was a United States Army brigade located at Fort Polk, Louisiana. The Brigade was tasked to improve the movement capabilities and rear area security for commanders at division level or higher. The Brigade has deployed units for combat operations in Afghanistan, Iraq, and for humanitarian assistance in Haiti after the 2010 earthquake.

The MEB is a tailored combined arms force with a headquarters staff designed to plan and execute protection, movement and maneuver, and sustainment tasks. It uses its subordinate units within their specialties to conduct maneuver support operations in its area of operations (AO) and within the broader AO of the organization it supports. The MEB provides added security and defense for other units and enhances freedom of action for the supported higher command. The capability to synchronize maneuver support operations and support area operations under the MEB provides a unique set of capabilities to other Army, joint, and multinational elements. Aside from its headquarters element and the organic communications and logistics elements that form the basis for commanding, controlling, and supporting the brigade, the Brigade is a mission, enemy, terrain and weather, troops and support available, time available, and civil considerations-dependent organization. The MEB leverages the current modular principles and the "plug-and-play" nature of current forces to apply the right force for the mission. Typically, but not exclusively, the MEB is composed of engineer, military police, chemical, air defense, and other units that routinely function together during protection, stability, and support operations.

Afghanistan 2008–2009
From Jun 2008 through Sep 2009, the Brigade was deployed to Afghanistan as part of Operation Enduring Freedom to act as the tactical command element for Bagram Airfield, a French infantry battalion and the Provincial Reconstruction Teams in the Parwan Province. The unit earned a Campaign Streamer embroidered "Consolidation II" and the Meritorious Unit Citation for this mission.

Defense CBRNE (Chemical, Radiological, Biological, Nuclear, and Explosive) Response Force 2011–2013
The Brigade was committed to the United States Northern Command and United States Army North as part of Joint Task Force-Civil Support to serve as the CBRNE Consequence Management Response Force, and served as an on-call federal response force for terrorist attacks and other natural or manmade emergencies and disasters. This assistance is termed "Defense Support of Civil authorities". This response is subject to the limitations of the Posse Comitatus Act. See also the National Response Framework.
