The Marine Corps currently has four permanent caable units: 1 Civil Affairs Group (1CG), 2 CETA, 3 CETA and 4TH CAG, all part of the Marine Forces Reserve Headquarters Group. The 5th Civil Affairs Group and the 6th CAG were provisionally established in 2005-06 for Operation Iraqi Freedom, but both were deposed after a deployment to Iraq.  Artillery units reinforced by Marine CMs were also deployed to Iraq and Afghanistan in 2006-07 to serve in civil affairs.  In 2010, the Marine Corps added a Civil Affairs Division to each of the three Marine Expeditionary Forces. The Marine Corps assigns civil affairs as the primary military specialty for conscripts and as an additional specialty for officers. The Marine Corps uses its own doctrine for civil affairs and directs the Marine Corps School of Civil-Military Operations (MCCMOS) at Marine Corps Base Quantico to train Marines in civil affairs. MCCMOS also offers career progression courses and MOS for CMO planners (officers) and CMO chiefs (SNCO). In addition, MCCMOS offers a course on the Stability Assessment Framework and a Civil Affairs Integration Course. The civil affairs team locates civilian resources to support military operations, minimize civilian interference, and facilitate humanitarian relief activities.
In turn, through civil affairs, local communities and groups have the opportunity to access the mission, which they may perceive as distant and militarized. Civil affairs can be a bridge, meaning that groups that previously would not have dared to approach the mission`s heavily guarded doors and request a conversation with mission leaders on the ground, civilian or military, can now turn to the UN as guests rather than requesters. The mission is inevitably enriched by this type of dialogue, and civilian leaders are often the best mediators. Maritime Civil Affairs Teams (MCQs) reduce the impact of military operations imposed during peace and periods of declared war, and increase the impact of civil humanitarian assistance (HCA) and emergency operations in support of security cooperation plans in theatre. Within the United States Army, civilian reserve units are administered by the United States Army Civil Affairs and Psychological Operations Command (Airborne) or USACAPOC(A), a subordinate of the U.S. Army Reserve Command. USACAPOC(A) contains units for psychological operations (PO) and civil affairs (CA), which consist of elements of the army reserve. .
