Which of the following is a type of defensive coverage included in active air defense?

The correct response highlights various types of defensive coverage found in active air defense, specifically focusing on Area Defense, Point Defense, Self Defense, and High-Value Air Asset (HVAA) protection.

Area Defense aims to protect a designated geographical area from air threats, allowing for a broader range of coverage. Point Defense, on the other hand, is more focused, concentrating on defending a specific site or asset from potential air attacks. Self Defense includes measures taken to protect the forces directly engaged in combat, while HVAA protection is critical for safeguarding vital air assets essential to the mission. Each of these components works together to form a robust strategy for countering aerial threats and ensuring operational effectiveness.

The other options do not relate directly to defensive coverage in the context of active air defense. Covert operations usually refer to secretive missions rather than direct defense strategies against aerial threats. Offensive air missions focus on attacking enemy capabilities rather than defending against them. Preparation for ground warfare does not specifically address air defense and instead pertains to strategies and tactics related to land forces. Therefore, the emphasis on defensive strategies in the chosen answer is correctly aligned with the principles of active air defense.
