Which option defines the Company Grade Officer ranks?

• A. Field Grade Officer (O-4 to O-6)
• B. Company Grade Officer (O-1 to O-3)
• C. General Officer (O-7 to O-10)
• D. Senior Officer (O-5 to O-6)

Answer: (B)

Company Grade Officers are the junior officers, defined by pay grades O-1 through O-3, which correspond to the ranks of second lieutenant, first lieutenant, and captain. This group sits below Field Grade Officers (O-4 to O-6) and General Officers (O-7 to O-10). The term comes from historical practice, where officers at this level typically commanded at the company level. So, identifying the range O-1 to O-3 best defines Company Grade Officer ranks. The other ranges describe higher levels of leadership.
