High Quality Content by WIKIPEDIA articles! Task Force 121 is a classic example of the United States' 'Joint Task Force' concept of conducting special operations. It is organized in a manner similar to Task Force Ranger, which was used during the Battle of Mogadishu in 1993 - Delta Force personnel or other Special Operations Forces supported by high quality light infantry, usually men from the 75th Ranger Regiment. TF121 is a multi-service force commanded by U.S. Air Force Brigadier General Gregory L. Trebon. The spearhead of the force is a forty-man team made up of operators from the U.S. Army's Delta Force/Green Berets, U.S. Army's INSCOM intelligence unit , the U.S. Navy's DEVGRU, U.S. Army Rangers, the CIA's Special Activities Division, and the U.S. Army's 160th Special Operations Aviation Regiment (a.k.a. SOAR, Nightstalkers.) Other Special Operations contributions will include U.S. Air Force Combat Controllers, and U.S. Air Force Pararescue.
