The Pentagon has begun notifying 43,000 Reserve and National Guard troops to be prepared for a year-long deployment in Iraq. The reserves will be used as part of a new Pentagon plan to rotate troops in and out of Iraq. The Pentagon also announced that the Marines will soon return to Iraq to help re-enforce the Army in the occupation and reconstruction. The Marines played a major role during the invasion but were pulled out by September. The New York Times reports the Pentagon now plans to reduce the number of U.S. troops in Iraq from 130,000 to just over 100,000 over the next year.
