With a color casing ceremony Thursday at King Field House, Fort Riley’s 2nd Armored Brigade Combat Team, 1st Infantry Division, marked its official deployment to the Republic of Korea.

The brigade furled its flags, known as the “Colors,” into protective sheaths, signaling its suspension of operation at Fort Riley.

The deployment is part of a regular rotation of forces to support the U.S. Indo-Pacific Command and Republic of Korea-U.S. Alliance.

There, soldiers are assigned to promote security cooperation and respond to and mitigate issues that may arise between international forces.

Around 4,500 soldiers from the brigade will be deployed for about nine months, replacing the 3rd Brigade Combat Team, 1st Cavalry Division, from Fort Hood.

Troops will head out in the coming weeks, and the brigade will return to Fort Riley at the end of its deployment.
