Which term is defined as the line of advance assigned for the purpose of control, extending toward the enemy?

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

Answer: (B)

The line of advance assigned for control extending toward the enemy is the axis of advance. This line provides the directional path along which the force moves to reach its objective and serves as a reference for maneuver, fire coordination, and assigning responsibilities across units as they push forward. It helps ensure everyone is moving in the same general direction and that fires and maneuver are synchronized toward the enemy.

FEBA marks the forward edge of the battle area, not the path of advance. The engagement area is the zone where a unit will conduct engagement with the enemy, not the directional line for maneuver. Boundaries define limits of operation or responsibility, not the specific line used for guiding the attack toward the enemy.
