United States Forces-Afghanistan
United States Forces-Afghanistan (USFOR-A) is the senior U.S. military headquarters in Afghanistan, with a complex structure and reporting chain. It is commanded by GEN Stanley McChrystal, who also commands the NATO International Security Assistance Force (ISAF) There are two overt and one covert subcommands.
The main overt U.S. combat force in Afghanistan has had many names, beginning with Task Force 180 (TF180), but now TF101, to show its base in the 101st Airborne Division, which is both a subcommand of ISAF and United States Central Command. TF180 is oriented towards counterinsurgency, or "people-centric" operations providing security for the Afghan people.
USFOR-A also Combined Security Transition Command - Afghanistan, which is responsible for joint training and other partnerships with Afghan Security Forces.
There is also a substantial organization from United States Special Operations Command, especially the highly classsified Joint Special Operations Command, which is oriented toward counterterrorism rather than counterinsurgency. Their techniques include direct action by means of raids and ambushes against terrorists, as well as special reconnaissance to guide aircraft, drone and missile strikes. Paramilitary units of the Central Intelligence Agency probably report to this organization, as well as to their own headquarters.
