A feature within the defensive zone of greatest importance to overall defense integrity is what?

• A. Key Defense Point
• B. Main Direction
• C. Depth
• D. Integration

Answer: (A)

The key idea here is the anchor of the defense—the point that holds the defensive zone together and gives the entire system coherence. The Key Defense Point acts as the central hub of the defense: it concentrates decisive fire, provides observation and early warning, and serves as a focal point for command, control, and the deployment of reserves. Its stability keeps adjacent positions in line and prevents a collapse of the defense’s integrity even if other areas come under pressure. If this point falters, the whole defensive arrangement tends to unravel, because fires, reinforcement, and coordination rely on that central anchor.

Depth, main direction, and integration are important aspects of a defense, but they hinge on a solid anchor. Depth creates layers to absorb and slow the attacker, main direction guides where the enemy will be focused, and integration ensures different arms and units work together. None of these can maintain overall integrity as effectively on their own if the Key Defense Point isn’t secure and effective.
