What collar device does a Lieutenant Colonel wear?

A Lieutenant Colonel wears a silver oak leaf as their collar device. This insignia is distinctive and serves as a visual identifier of the officer's rank within the military hierarchy. The silver oak leaf is commonly recognized across various branches of the armed forces and signifies the rank of Lieutenant Colonel, which typically falls between Major and Colonel.

Understanding the insignia is crucial as it helps convey rank and authority, allowing for proper protocol and respect within military settings. In contrast, the other options represent different ranks; for example, a gold oak leaf signifies a Major, a silver eagle represents a Colonel, and a silver star is associated with a General. This knowledge is essential for anyone studying military ranks and their corresponding insignias, ensuring clarity in communication and organizational structure.
