Topeka ? About 700 soldiers from Fort Riley are returning to Iraq for their second tour of duty, officials here said Wednesday.

Post spokeswoman Deb Skidmore said the soldiers were with the 1st Battalion, 41st Infantry, 3rd Brigade, 1st Armored Division. The soldiers will be leaving within the next 70 days and assigned to the 2nd Brigade, 10th Mountain Division, out of Fort Drum, N.Y.

Currently, 3,700 Fort Riley soldiers are in Iraq, including the 1st Brigade, 1st Armored Division, which is scheduled to return to Kansas in the fall.

Secretary of Defense Donald Rumsfeld has ordered more U.S. forces to Iraq to replace units that were ordered to stay there longer than their original 12-month tours of duty. Among those units told to stay were the 1st and 2nd Battalion of the 1st Armored, based in Germany.

Fort Riley is home to the 1st Brigade, 1st Armored, which returned from Iraq to the 100,000-acre central Kansas post in April.

Skidmore said the infantry battalion was the second from Fort Riley to make a second tour in Iraq, joining 200 soldiers from the 82nd Medical Company of the 937th Engineer Group, which has been in Iraq for its second tour since February.
