Final answer:
The size of the CPO collar device is 1 1/4 inches wide, with specific positioning requirements to maintain uniformity in the U.S. Navy.
Step-by-step explanation:
The size of the CPO collar device, referring to the Chief Petty Officer insignia in the United States Navy, is regulated to ensure uniformity.
The insignia is to be 1 1/4 inches wide. The fouled anchor design within the collar device, a symbol traditionally used by the Navy, is positioned in such a way that the shank of the anchor is 1 inch from the collar tip, and the anchor's stock is parallel to the front edge of the collar.
