PINR - Current U.S. Troop Levels in Iraq Are Unsustainable: "A report released by the Congressional Budget Office recognized...that the active Army would be unable to maintain current troop levels in Iraq 'beyond about March 2004 if it chose not to keep individual units deployed to Iraq for longer than one year without relief.' Indeed, the Pentagon will now be relying on reserve soldiers for combat missions rather than for their traditional combat support roles."
