Which term is the line of advance assigned to control movement toward the enemy?

• A. Axis of Advance (AOA)
• B. Forward Edge of the Battle Area (FEBA)
• C. Boundary (MCM)
• D. Engagement Area (EA)

Answer: (A)

The line of advance is the axis of advance, the primary line along which a force moves toward the enemy and concentrates its effort to close with and attack. It sets the direction for maneuver and fires, guiding both the movement of units and the synchronization of supporting fires so that all elements converge on the objective. By choosing the axis of advance, commanders shape how terrain, obstacles, and enemy dispositions are exploited to maintain momentum and achieve surprise or massed effects along a single approach.

FEBA, the forward edge of the battle area, marks the front boundary of our own force relative to the enemy and is used for positioning and deconfliction, not for directing movement toward the enemy. A boundary (MCM) isn’t the line used to control movement toward the enemy. An engagement area is where we expect to fight and control engagements once contact occurs, not the route of maneuver to reach the enemy.
