Task Force Faith and Operation Undertone were both components of which branch of the U.S. military?
Task Force Faith Task Force Faith, also known as Task Force Maclean (and by its official designation, Regimental Combat Team 31 (RCT-31)) or the Polar Bear Regiment (), was a United States Army unit destroyed in fighting at the Battle of Chosin Reservoir during the Korean War between 27 November – 2 December 1950. It comprised primarily infantry, artillery, and tank units from the 7th Infantry Division, numbering approximately 3,000 soldiers. Of these, about 600 were KATUSAs (Korean Augmentee To the U.S. Army). The name Task Force Faith was originally coined by a U.S. Army historian; however, the unit was never known by this name. RCT-31, which consisted of the 31st Infantry Regiment and supporting units, had the 1/31 Infantry detached and the 1/32 Infantry (from the RCT-32) added, and the designation RCT-31 was never changed.
Joint Interagency Task Force West Joint Interagency Task Force West (JIATF-W, or JIATF West) is a standing United States military joint task force with the mission of combating drug-related transnational organized crime in the Indo-Asia-Pacific. JIATF West's area of responsibility (AOR) is that of United States Pacific Command (USPACOM). JIATF West is one of two Joint Interagency Task Forces with a counter-narcotics mission. The other is Joint Interagency Task Force South. The task force is run as USPACOM's "executive agent" for counterdrug activities providing support to partner nation law enforcement. Approximately 166 active duty and reserve U.S. military forces; Department of Defense civilian employees; contractors; and U.S. and foreign law enforcement agency personnel are members of the task force.
