Which of the following operations is used to support a larger maneuver force by creating favorable conditions?

The operation that supports a larger maneuver force by creating favorable conditions is the Mobile Defense. This type of defense focuses on retaining and exploiting positional advantage while allowing for the maneuver of forces to disrupt or defeat the enemy. In a Mobile Defense, the defending force maintains contact with the enemy through reconnaissance and skirmishes, while also maneuvering to create opportunities for decisive engagement. By striking the enemy at the most advantageous point or at a moment of their weakness, the defending force can help shape the battlefield and set conditions favorable for the main body of friendly forces.

This operation exemplifies how a defending force can facilitate a larger offensive action through dynamic maneuvers rather than just static defense. The Mobile Defense effectively combines direct and indirect fires, reinforcing the adaptability needed to disrupt enemy advances while positioning for an eventual counterattack.

In contrast, the other operations listed do not focus primarily on creating conditions for a larger maneuver force. Area Defense is about maintaining a strong defensive position without the flexibility seen in Mobile Defense. Retrograde operations are mainly about withdrawal and might not create advantageous conditions but rather aim to preserve fighting capabilities. Support by Fire involves providing covering fire to assist maneuver elements but does not inherently create battlefield conditions as comprehensively as Mobile Defense does.
