What is the insignia for the rank of Major in the Marine Corps?

In the Marine Corps, the rank of Major is denoted by the insignia of a silver oak leaf. This distinguishing emblem is used to signify the officer's rank within the Marine Corps hierarchy and aligns with the common practice across the military services in the United States, where an oak leaf symbolizes a field grade officer rank. The silver color specifically represents the Major rank, which sits between Captain and Lieutenant Colonel in terms of authority and responsibility.

Other insignia options represent different ranks: two silver bars correspond to the rank of Captain, while a single silver star symbolizes the rank of Brigadier General. The gold oak leaf, typically used to represent the rank of Lieutenant Colonel, does not match the Major insignia. Understanding the symbolism behind these ranks and their visual representation is crucial for recognizing the structure of the Marine Corps and promoting effective leadership and communication within the ranks.
