Which staff advises the commander and staff in a particular subject?

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

Answer: (A)

The question is about who provides expert, subject-specific advice to the commander and staff. Special Staff are the specialists brought in to advise on a particular topic—legal, medical, financial, or other areas requiring deep, focused knowledge. They contribute analysis and recommendations to inform decisions, without being part of the main line organizations that run operations or logistics. By contrast, the Principle Staff handles the core functional areas (like operations, intelligence, logistics, and personnel), Personal Staff serves the commander as personal aides, and Chaplain provides religious support and morale. So the term that best fits “advises the commander and staff in a particular subject” is Special Staff.
