Which joint function secures and defends the effectiveness and survivability of mission-related entities?

• A. Information
• B. Protection
• C. Fires
• D. Movement and Maneuver

Answer: (B)

Protection focuses on keeping people, equipment, information, and facilities safe from threats, so the mission can be carried out. By reducing vulnerability, providing security measures, and enabling rapid responses to shocks or attacks, protection preserves the effectiveness and survivability of mission-related entities. This includes physical security, force protection, safety, and continuity of operations, such as perimeter defenses, access control, and convoy security, which help ensure missions can proceed even under threat. While other functions play important roles—information manages data, fires defeats threats, and movement and maneuver shapes positioning—protection is the element dedicated to defending those assets and sustaining operation under risk.
