Define Combat Troops

I've been on John Kerry's email list ever since my name was passed to him when Howard Dean pulled out of the 2004 race for president. Today I have an email from him encouraging me to sign on as a "co-sponsor" of his bill to set a timetable for troop withdrawal from Iraq. While I think troop withdrawal is a great idea, I have a problem with the wording he used in one sentence of his email.
His email referred to Bush's "future presidents" remark at his press conference last month, but Kerry's email says this:
"I believe that American combat troops should come home from Iraq in 2006 - not the distant future as President Bush does."
Great, except that at the press conference, the question didn't refer to "combat troops." The question was, "will there come a day when there will be no more American forces in Iraq?"
Now I'll let my guard down here a bit. I don't trust Kerry one little bit, so it isn't surprising to me that he'd play a little word trick here on this very serious matter. He isn't the only Democrat playing this game. The truth is that there aren't very many Democrats supporting a complete withdrawal of all "American forces" from Iraq.
But just what does Kerry mean by "combat troops" and just who would remain after they are withdrawn?
