What is the horizontal distance from a defended asset at which a successful engagement denies an adversary's desired weapons effects?

• A. Overlapping Coverage
• B. Balanced Fires
• C. Keep-Out Range
• D. Early Engagement

Answer: (C)

Keep-out range is the horizontal distance from a defended asset within which your fires can deny the adversary’s desired weapons effects. It defines the boundary where an engagement can effectively prevent the attacker from achieving a successful attack. This makes it the right concept for describing the distance at which a successful engagement denies the enemy’s intended effects. The other terms describe different aspects of defense—overlapping coverage is about redundancy across shooters, balanced fires is about distributing fires evenly, and early engagement is about firing sooner to disrupt the attacker—so they don’t specify the denial-distance boundary used to prevent the adversary’s effects.
