What is the airspace known as the airspace of defined dimensions within which responsibility rests with low-to-medium-altitude surface-to-air missiles?

• A. HIMEZ high-altitude missile engagement zone
• B. JEZ joint engagement zone
• C. LOMEZ Low altitude missile engagement zone
• D. HIDACZ high-density airspace control zone

Answer: (C)

This item focuses on how air defense sectors assign engagement responsibility by altitude. A Low Altitude Missile Engagement Zone designates airspace of defined dimensions within which responsibility rests with low-to-medium-altitude surface-to-air missiles. This arrangement ensures threats within the lower-altitude band are handled by missiles suited for that range, while higher-altitude threats are addressed by other assets. The other terms refer to different concepts: a high-altitude missile engagement zone is for higher-flying targets, HIDACZ concerns high-density airspace control, and a joint engagement zone covers coordinated engagement authority across services. Therefore, the described airspace is the Low Altitude Missile Engagement Zone.
