What does Mix Deff describe?

• A. Employment of a combination of systems to protect asset
• B. Deployment of a single, long-range system
• C. Replacing assets with ground units
• D. Using air sorties exclusively

Answer: (A)

Mix defense describes employing a combination of air defense systems to protect assets. The idea is to layer sensors and shooters across different ranges and modalities, so the defense remains effective even if one element is degraded or overwhelmed. A mixed setup typically uses long-range sensors and missiles for early detection and high-altitude engagement, medium- and short-range systems for mid- and low-altitude threats, and close-in point defenses, all integrated to share tracking data and coordinate responses. This creates redundancy, expands engagement opportunities, and increases the overall probability of stopping a diverse threat set, from high-flying missiles to fast maneuvering aircraft and drones.

That’s why the other options don’t fit: relying on a single long-range system leaves gaps at closer ranges and against diverse threats; replacing assets with ground units ignores the airborne nature of the threats and the need for shields in the air domain; and using air sorties exclusively excludes the essential protective layer provided by ground-based air defense assets and their sensors.
