WTF?

From the Washington Post:

The number of Iraqi army battalions that can fight insurgents without U.S. and coalition help has dropped from three to one, top U.S. generals told Congress yesterday, adding that the security situation in Iraq is too uncertain to predict large-scale American troop withdrawals anytime soon.

How the fuck do two battalions go from fit to unfit, you ask.

Officials did not say specifically why two battalions are no longer rated at Level 1 and thus unable to operate on their own. They said generally readiness ratings can change for numerous reasons, such as if a commander resigns, or if more training is needed. Casey also said that the "Iraqi armed forces will not have an independent capability for some time."

Huh?
