What is the next rank after a Captain in the Marine Corps?

In the Marine Corps, the rank that follows Captain is Major. This rank is significant as it marks the transition from a company-grade officer to a field-grade officer. Captains typically command a company, while a Major can serve in various leadership roles, often overseeing larger units and operations.

The other ranks listed are higher than Major; Lieutenant Colonel is a rank above Major, while Colonel is a rank above Lieutenant Colonel. First Lieutenant, while it is an officer rank, is positioned below Captain and therefore is not the correct choice. Understanding the progression of ranks is important for recognizing the chain of command and responsibilities within the Marine Corps.
