Task Force Phoenix, or more properly known as Combined Joint Task Force Phoenix (CJTF Phoenix), was an international military formation. It was organized by the United States Central Command (CENTCOM) in 2003-2004 to train and mentor the newly created Afghan National Army/Afghan National Security Forces (ANSF) to establish and maintain law and order throughout Afghanistan using Embedded Training Teams or ETTs.
Immediately following the collapse of the Taliban regime, Soldiers from the 10th Mountain Division began the initial development of the Afghan National Army (ANA) as Task Force Phoenix.
One of the early mission statements for the formation appears to have been: "Coalition Joint Task Force PHOENIX executes a broad-based training, mentoring, and assistance program in order to enable the Afghanistan National Army (ANA) to field a mission-ready Central Corps NLT [No Later Than] June 2004."
The first units involved with TF Phoenix were from the 10th Mountain Division out of Fort Drum, New York. Once the 10th Mountain Division rotated home the mission was assumed by units of the Army National Guard and other members of the coalition. Phoenix II built up the first Afghan Corps – the Central Corps, now 201st Corps (Afghanistan) - in Kabul, Afghanistan. Phoenix II was provided by the 45th Infantry Brigade-Oklahoma Army National Guard. Task Force Phoenix II's base support battalion served as the logistics command for the Afghan National Army, providing all logistics support for an army conducting country-wide combat operations. During this rotation, the brigade grew the size of the Afghan National Army to over 14,000 as well as fielding a corps-sized force ahead of schedule. In August 2004, the brigade was replaced in this mission by the 76th Infantry Brigade-Indiana Army National Guard, and subsequently returned home to the United States. Phoenix III took on the daunting task of splitting that Corps into five separate Corps and locating them throughout the country at five strategic centers. Phoenix IV (53rd Infantry Brigade Combat Team (United States) Florida Army National Guard) worked to build up those Corps to full strength. TF Phoenix IV's Training Assistance Group (209th Regiment-Nebraska Army National Guard and 211th Regiment-Florida Army National Guard) stationed at Camp Alamo (inside the Kabul Military Training Center) implemented major improvements to both Basic and Advanced Individual Training programs. Task Force Phoenix V ( 41st Infantry Brigade-Oregon Army National Guard) was the fifth ANA training rotation. The mission continued to expand with TF Phoenix V taking on additional responsibilities associated with training and supporting the Afghan National Police (ANP), as well as continuing to train and mentor the growing ANA. TF Phoenix V was composed primarily of soldiers from the U.S. Army National Guard, with members representing 49 of the 50 states. In addition, they had elements from the regular and reserve components personnel from the Navy, Air Force and Marine Corps attached. Later, the responsibility for the Phoenix missions were assigned to the 27th Brigade Combat Team of the New York Army National Guard took command of Task Force Phoenix on 19 April 2008 from the 218th BCT, South Carolina Army National Guard. They were relieved on 19 December 2008 by the 33rd Brigade Combat Team Illinois Army National Guard. In 2009, the 48th Infantry Brigade Combat Team Georgia National Guard assumed command of Task Force Phoenix IX.
