About 500 soldiers from the 1st Cavalry Division will deploy to Afghanistan this summer, the Army announced Tuesday.

The deploying soldiers will be from the division headquarters and its Sustainment Brigade headquarters.

Once in Afghanistan, the Fort Hood, Texas-based soldiers will replace the 10th Mountain Division headquarters at Bagram Airfield as the National Support Element.

The 1st Cavalry Division also will take responsibility for Train, Advise and Assist Command-East.

"First Team troopers are trained, well-led and ready to accomplish assigned missions in support of Operation Freedom's Sentinel," said Maj. Gen. John Thomson, commanding general of the division, in a statement.

In addition to the headquarters soldiers, about 1,000 soldiers from the 3rd Cavalry Regiment, also from Fort Hood, will deploy to Afghanistan. These soldiers, whose deployment was announced earlier this month, will leave in the spring, and their tour is part of the regular rotation of forces in Afghanistan.
