• A. Staff Corps are specialists in specific fields crucial to operational readiness, such as Chaplain, Civil Engineer, and Dental.
• B. Staff Corps officers are not commissioned and serve only in administrative roles.
• C. They are the primary combat arms units of the Navy.
• D. Staff Corps officers are restricted to public affairs duties.

Answer: (A)

Staff Corps are professional specialists whose expertise directly supports the Navy’s operational readiness. They are commissioned officers who practice in specific fields, providing essential services that enable missions to be carried out effectively. Examples like Chaplain, Civil Engineer, and Dental illustrate how these officers contribute in distinct professional domains—spiritual guidance and morale, engineering and infrastructure, and healthcare—beyond traditional combat roles.

This description is accurate because Staff Corps officers are not limited to administrative duties or non-commissioned status, nor are they the primary combat arms units or restricted to public affairs. They bring specialized expertise to the fleet and shore commands, ensuring the Navy can plan, execute, and sustain operations with professional support across multiple disciplines.
