OEF, yes. Operation Enduring Freedom, or the U.S.-led coalition activities, coordinate very closely with the International Security Assistance Force. When we established the operations plan currently in force—operations plan 10302—there was a very distinct command and control relationship established between OEF and ISAF.
Now, the coalition is doing counterterrorist operations. They are hunting Taliban and al-Qaeda. ISAF is not. But their activities are coordinated, through Commander ISAF, in a dual-headed relationship with what we call the deputy commander of security, the American head of the special operations forces in Afghanistan.
All of their activities are coordinated with NATO, or at least they're aware of them. The Operation Enduring Freedom forces can come to the assistance of ISAF, if required, in extremist situations. I might add that we don't do it the other way around. We don't do counterterrorist operations; we do anti-terrorist or force protection operations in terms of the Taliban.
The air strikes, though, are called in through a very well-established air strike request system. It goes from the commander on the ground to the air support operations centre to what we call the deputy commander air, an officer in the staff of Commander ISAF in Kabul. Those requirements are vetted. It may not always be air strikes; it may be artillery, for example. Those decisions are made through a very well-established set of criteria.
If the air strikes are required, the requests for support go through the combined air operations centre in Qatar, which then assigns the mission based on what aircraft are available, the requirements of the mission, and so on.
