91st Civil Affairs Battalion (Airborne)

The 91st Civil Affairs Battalion (Airborne) was first constituted on 25 June 1969 in the Regular Army as the 1st Civil Affairs Battalion and activated on Okinawa. It was inactivated on 30 June 1974 at Fort Bragg, North Carolina.

Beginning in FY 2006 with the provisional activation of the 95th Civil Affairs Brigade, the US Army began expanding civil affairs capabilities within the US Army Special Operations Command. One civil affairs battalion was activated along with the 95th Civil Affairs Brigade (Airborne) in 2007, and another was activated in 2008. Army Special Operations Command continued its growth and reorganization with the 91st Civil Affairs Battalion (Airborne), which went into carrier status concurrent with the activation of the 98th Civil Affairs Battalion (Airborne) in 2008, with an activation date expected in 2009.

The unit, which had been redesignated while inactive on 14 March 2006 as the 91st Civil Affairs Battalion was formally reactivated on 16 March 2009 at Fort Bragg, North Carolina. The Battalion's regional focus was to support operations within the US European Command (EUCOM) and Africa Command (AFRICOM) areas of responsibility. Another battalion was expected to be activated that would take up the EUCOM portion.
