Upon returning to Ft. Hood, Texas from Operation Iraqi Freedom, the Battalion was deactivated in late 2007 and was reactivated on April 9, 2008, at Ft. Carson, Colorado.

This was part of a major realignment involving the 4th Brigade Combat Team, 4th Infantry Division. The Brigade Combat Team was reflagged as the 4th Brigade Combat Team, 1st Cavalry Division. The 1st Battalion, 12th Infantry Regiment was reflagged as the 5th Battalion, 82nd Field Artillery Regiment. The 2nd Brigade Combat Team, 2nd Infantry Division at Fort Carson, Colorado was reflagged as the 4th Brigade Combat Team, 4th Infantry Division.

As part of this reflagging, the 4th Brigade Combat Team transitioned from a Heavy Brigade Combat Team to an Infantry Brigade Combat Team. As a result, 2nd Battalion, 77th Field Artillery was reactivated as a light artillery battalion with towed howitzers rather than a self-propelled howitzer battalion as it had been previously organized.

The 2nd Battalion, on order, will deploy from Fort Carson, Colorado and provide direct field artillery fires and execute stability operations.
