The IDC is chaired by the ________ or designee.

• A. Installation Commander
• B. Base Commander
• C. Integrated Defense Committee Chair
• D. Security Forces Commander

Answer: (A)

The key idea is who leads the cross‑functional effort that coordinates on‑base defense. The Integrated Defense Committee is a joint body that brings together security, emergency management, operations, and other base agencies to plan and respond to threats. That leadership role sits with the Installation Commander, or someone the commander designates, because this position holds the overall authority and accountability for the installation. They can set priorities, marshal resources, and ensure unified action across all units and tenant organizations, which is essential for an integrated defense posture. A designee can stand in when necessary to maintain continuity.

The other options don’t fit as well because the Security Forces Commander focuses on a specific function (security force operations) rather than the whole installation, and the term for a separate “Integrated Defense Committee Chair” isn’t a standard appointment. The Base Commander is typically the same person as the Installation Commander in many contexts, but the wording used here points to Installation Commander as the authoritative chair.
