U.S. to send 3,700 troops to Baghdad

The U.S. command announced Saturday that it was sending 3,700 troops to Baghdad to try to quell the sectarian violence sweeping the capital, and a U.S. official said more American soldiers would follow as the military gears up to take the streets from gunmen.

The 172nd Stryker Brigade, which had been due to return home after a year in Iraq, will bring quick-moving, light-armored vehicles to patrol this sprawling city of 6 million people, hoping security forces respond faster to the tit-for-tat killings by Shiite militias and Sunni Arab insurgents.

The U.S. military hopes more armor will intimidate gunmen, who in recent weeks have become more brazen in their attacks.

“This will place our most experienced unit with our most mobile and agile systems in support of our main effort,” said Gen. George W. Casey Jr., the top U.S. commander in Iraq. “This gives us a potentially decisive capability to affect security in Baghdad.”
