Which rank corresponds to O-8 in the Marine Corps?

In the Marine Corps, the rank corresponding to O-8 is Major General. This rank is a two-star general officer role that signifies a significant level of leadership and responsibility within the military hierarchy. An individual at this rank typically oversees a major operational unit, and their duties may include strategic planning and coordination of large-scale military operations.

To provide further context, the other ranks listed do not match the O-8 classification. Captain is an O-3 rank, Colonel is an O-6 rank, and Brigadier General, while closely related to Major General, is actually O-7 because it is a one-star general officer rank. Understanding the development and structure of ranks in the military is essential for recognizing leadership roles and the chain of command within the armed forces.
