From an A.P. piece about the state of Iraqi forces:
Numbers of trained Iraqi troops don't provide a complete picture. The U.S. military no longer supplies figures on how many have been fully equipped with armor, weapons, vehicles and communications gear.
The piece has plenty of other good nuggets, including:
The actual numbers in the National Guard, however, have ebbed and flowed between 35,000 and 43,000 and are now around 36,000, according to U.S. government figures. Over the last six months, the Guard has lost 10,000 personnel, although some have been replaced through recruiting.
