Two brigades from Fort Carson, Colorado, are on tap for a spring 2018 deployment to Afghanistan, the Army announced Thursday.

The 1st Stryker Brigade Combat Team and 2nd Infantry Brigade Combat Team, 4th Infantry Division, will be part of a regular rotation in support of Operation Freedom’s Sentinel, according to two releases from the Army’s Office of the Chief of Public Affairs.

“The 1st Stryker Brigade Combat Team, 4th Infantry Division is trained and ready for any mission in the Army. Our formation of soldiers are fit, inspired, disciplined, and trained,” Col. Monté L. Rone, commander of 1st Stryker Brigade Combat Team, said in a release. “We couldn’t do this without our families and owe a special thanks for their willingness to stand by our most precious resource ― The American Soldier.”

Rone’s brigade will replace 4th Brigade Combat Team, 25th Infantry Division, who have been in Afghanistan since September.

“The 2nd Infantry Brigade Combat Team of the 4th Infantry Division has a proud deployment history in support of operations in Afghanistan,” said Col. David Zinn, commander, 2nd Infantry Brigade Combat Team, in a release. “Our War Horse soldiers are trained, ready, and are honored that the Army has selected our unit for the deployment.”

That brigade will replace 1st Infantry Brigade Combat Team, 82nd Airborne Division, who arrived in-country last summer.
