The Foremost limit of the battle area that conveys the commander’s intent in defense is known as what?

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

Answer: (A)

The line that marks how far the defense extends and communicates how the commander intends to fight is the Forward Edge of the Battle Area. This boundary defines the foremost limit of where the defender expects to operate and engage the enemy, sending a clear signal to all units about where the battle space begins and where the defensive effort will be concentrated. It helps subordinate units position themselves, assign fires, and coordinate reconnaissance and security tasks to support the defender’s plan.

Engagement Areas are specific sectors within the defense where the unit expects to fight and concentrate fires, not the overall forward limit of the battle space. The concept of a boundary like that described here isn’t the same as a general boundary term, and the Axis of Advance refers to the enemy’s expected approach path, not the defender’s forward limit.
