U.S. forces formally transferred responsibility of Contingency Operating Location McHenry in Kirkuk, Iraq to the Iraqi government during a ceremony on May 15, 2011. COL McHenry had been established in 2003 and was one of the oldest U.S. bases in Iraq. Responsibility was transferred from the U.S. Army's 1st Battalion, 14th Infantry Regiment to the Iraqi Army's 46th Brigade, which will continue operations from the base. The transfer represents a milestone as the U.S. completes its mission in Iraq and Iraqi forces assume full security responsibility.
