another nine-month rotation. Current structure On 15 July 2005, the 1st Cavalry Division transitioned to the Unit of Action modified table of organization and equipment (MTOE). No longer are there battalion-sized elements made up purely of armor and/or infantry battalions. Brigades are now composed of combined arms battalions, meaning every maneuver battalion combines infantry and armor, excluding the reconnaissance squadrons. The division's artillery battalions are assigned to all three of the Brigade Combat Teams. 1st Cavalry Division consists of a division headquarters and headquarters battalion, three armored brigade combat teams, a division artillery, a combat aviation brigade, and a division sustainment brigade.
