Which staff works directly for the commander and includes aides-de-camp, SgtMaj/CMC, and personal secretaries?

• A. Personal Staff
• B. Special Staff
• C. Principle Staff
• D. Chaplin

Answer: (A)

The key idea here is who directly supports the commander on a day-to-day basis. The personal staff is the group that works closest to the commander, handling personal and administrative duties and serving as the direct extension of the commander’s office. Aides-de-camp manage the commander's schedule and communications, the senior enlisted adviser (SgtMaj or Commandant’s Sergeant Major) provides the top enlisted guidance and liaison, and personal secretaries handle correspondence and routine admin. These roles are all about enabling the commander to lead effectively by staying directly connected to the commander's needs.

By contrast, special staff provide specialized expertise (such as chaplains, medical, legal, etc.) and are not tied to the commander’s personal office. The main or principal staff comprises the core planning and functional offices (like operations, intelligence, logistics) that support the wider command but not the commander's personal day-to-day work. So, the group described—aide-de-camps, the SgtMaj/CMC, and personal secretaries—fits best with the personal staff.
