The U.S. military claims it has completed its troop surge for the counter-insurgency mission in Baghdad.
Officials said the fifth and final brigade of the troop surge has arrived in Baghdad. They said the brigade would be fully operational by mid-July for the counter-insurgency mission in the Iraqi capital.
"We are starting to see a shift in momentum that comes with having additional forces on the ground," Brig. Gen. Perry Wiggins, deputy operations director at the Joint Chiefs of Staff, said.
The surge has been accompanied by a sharp rise in U.S. casualties. The U.S. military has reported 119 casualties for May 2007, the highest monthly toll since November 2004.
