That leads me to another question, and it may take a little bit longer.
Strategy, obviously, is at the national level or theatre level. We're talking about tactics, and tactics can change, as you say, because of different circumstances. What kind of thing would drive a change in tactics in southern Afghanistan, and how would you manage that as a commander of CEFCOM in terms of NDHQ's and your input, ISAF's input, and the battle group's input?
