Jackson }} The United States Marine Corps' Anti-Terrorism Battalion (AT BN) was a specialized anti-terrorist task unit that would deploy on a short notice in response to terrorist attacks during the Global War on Terror. Anti-Terrorism Battalion is now a disbanded unit of the United States Marine Corps. MissionIn response to the 9-11 attacks the mission of the Anti-Terrorism Battalion was to rapidly deploy specially trained advanced infantry, intelligence personnel, support elements, and sustainable forces to detect, deter, defend, and conduct initial incident response to combat the threat of terrorism worldwide. Rotational DutyAfter the September 11, 2001, the Marine Corps began rotating standard infantry battalions such as 3rd Battalion 8th Marines (3/8) through 6 month on-call assignments as the designated "Anti Terrorism Battalion" to meet short term/no-notice mission requirements. Examples included augmenting security at the American Embassy in Kabul, Afghanistan, with a rifle company for site security. These rotations required company and smaller size detachments, but removed the entire force of the 1,000 man infantry battalion from the main war fighting effort. This posed a problem for the Marine Corps as Operations Enduring Freedom (OEF) and Iraqi Freedom (OIF) began to require additional full strength infantry battalions to rotate in and out of theater at a higher rate. USMC AT BN ActivationThe permanent AT Battalion (AT BN) was activated Oct. 29, 2004, under the 4th Marine Expeditionary Brigade (Anti Terrorism) (4th MEB (AT)). The 4th MEB (AT) was deactivated in February 2006, on the same day Marine Corps Forces Special Operations Command stood up, and the AT BN was administratively transferred initially to the II Marine Expeditionary Force (II MEF), and then finally to the 2d Marine Division by March 2006. The AT BN initially consisted of;

Numerous Marines also augmented other requirements for National Police Training Teams (NPTT), Military Transition Teams (MiTTs), and MEF augmentation requests to other infantry units. Most Marines in the battalion completed two to three consecutive combat deployments in a single three-year tour of duty with the battalion as part of their initial 4-year enlistment contract. USMC AT BN DeactivationOn 13 July 2007, the active duty AT BN stood down in name and was reflagged as the 2nd Battalion 9th Marines as part of the increase in the size of the Marine Corps. USMCR AT BN ActivationIn 2007 the Marine Corps Reserve reactivated the AT BN to meet similar mission requirements for the 4th Marine Division that the active duty battalion had met.
