What rank is assigned to the O-1 pay grade?

• A. Captain
• B. Lieutenant
• C. Ensign
• D. Lieutenant Commander

Answer: (C)

The rank assigned to the O-1 pay grade is Ensign. This designation is specifically used within the United States Navy. An Ensign is the lowest officer rank, typically held by newly commissioned officers. Being at the O-1 level signifies that the individual has completed the necessary training and education, such as the Officer Candidate School (OCS) or a Naval Academy program, and has received their commission as a naval officer.

In the context of military rank structures, understanding the progression from O-1 is important as it sets the foundation for roles and responsibilities that will grow as an officer advances in rank. The other ranks listed correspond to higher pay grades: Captain is O-3, Lieutenant is O-2, and Lieutenant Commander is O-4. Hence, Ensign is the only rank that fits the O-1 designation accurately.
