The 886th Expeditionary Security Forces Squadron (ESFS) is a composite unit consisting of Security Forces Squadrons from around the world like the 72d Security Force Squadron, Tinker AFB Oklahoma and the 47th Security Forces Squadron, Laughlin AFB Texas. This ESFS is one of seven Air Force-led units to work at the Theatre Internment Facility (TIF) of Camp Bucca, which is located in the vicinity of Umm Qasr, Iraq. This unit, as well as the other six of its class, is tasked for the In Lieu Of (ILO) Army assignment to work as prison guards and force protection for Camp Bucca. The 886 ESFS is trained in the United States of America, but is mobilized to leave with as little as a month's notice of assignment.
On 3 May 2008 the 886th Expeditionary Security Forces Squadron was inactivated and remaining 886th personnel were transferred to the 586th ESFS which is in charge of Force Protection for Camp Bucca.
