6-135. A division commander normally assigns a reinforced BCT to conduct a division covering force battle in the absence of a corps covering force. A division-controlled covering force allows a division to seize the initiative from an attacking enemy force. The size and composition of the covering force depends on its mission, the enemy, the terrain, and forces available. These mission variables take on added significance and complexity, depending on the enemy course of action. The depth and width of the AO comprising the forward security area and the time required to prepare the MBA greatly influence covering force operations as well.
