Okay, yes. We were not surprised by the extension, in the sense that the various battle groups were already training. Every six months we have a new one starting to form, coalesce, and go through the training cycle. Approximately 90% of the folk currently deployed into Afghanistan come from the army, so whether or not it's 90% of 2,300, or 2,000, or 1,800, it's a matter of scale.
In terms of the duty-ready organizations, the air force, in their response to NORAD, with their ready ships, the transport-ready aircraft, the transport aircraft, and the fighters, have very sophisticated mechanisms for keeping their aircraft on alert status. I'm not going to say anything more about that, because you have a real expert coming in two days, the commander of the air force. The same is true of the navy, and the same is true of the army. Having said that, the units that we have on immediate reaction unit status are for domestic operations. There is a very small cadre that does planning for international operations, but considering the number of soldiers we have overseas, those training to go in, etc., we don't have much left to offer, unless we stop doing a whole bunch of things.
