What collar device represents the rank of Captain (CPT)?

The rank of Captain in the Navy is represented by the collar device known as two silver bars. This distinctive insignia is used across various branches of the military, with each branch having its own specific form of representation. In the Navy, the two silver bars symbolize the rank of Captain and are worn on the collar of the uniform.

The other options represent different ranks: the gold oak leaf is typically associated with the rank of Major, while the chevrons and diamond indicate a rank such as a First Sergeant or Staff Sergeant in other branches of the military. The exploding bomb device is associated with the Seaman or enlisted ranks. Understanding these insignias is crucial for recognizing rank and structure within Navy operations.
