For the 1820 Billet and Rank in CSG Staff, which combination is listed?

• A. COMMO O4, N6 O5
• B. N6 O5, COMMO O4
• C. N6 O4, COMMO O5
• D. N6 O5, COMMO O5

Answer: (B)

Understanding billets and their rank requirements on a Carrier Strike Group staff helps ensure the right balance of experience and authority across key positions. N6 is the directorate that handles communications, networks, and information functions, and at this level the officer in charge is typically at the O-5 (Commander) grade. COMMO, the Communications Officer, is a specialized role that is commonly filled by an O-4 (Lieutenant Commander). So the pairing where N6 is O-5 and COMMO is O-4 aligns with standard staffing practices, providing the necessary senior oversight for the directorate while keeping the communications role at a suitable, capable rank. Swapping these ranks would place a more junior officer in the higher-visibility N6 role or an more senior officer in the COMMO role, which would not fit the typical distribution for these billets.
