If an officer holds the rank of Lieutenant Colonel in the Marine Corps, what insignia do they wear?

In the Marine Corps, the insignia worn by a Lieutenant Colonel is a silver oak leaf. This distinctive insignia helps to easily identify the rank of the officer. The design of the insignia is significant in military tradition, where the oak leaf symbolizes strength and endurance, traits that are important for leadership roles within the armed forces.

The alternative options present different ranks and their corresponding insignia. For example, the gold oak leaf symbolizes the rank of Major, while two silver bars represent the rank of Captain. A single gold bar indicates the lowest officer rank of Second Lieutenant. Understanding these differences in insignia helps in recognizing the hierarchy within the Marine Corps and other branches of the military.
