The chevrons for the field uniforms and the overcoat are the same as for other noncommissioned officers of the Marine Corps with the addition of the cornet for second leader, the star for drum major and the lyre for musicians. The chevrons for the special full dress and full dress coats are of the same size and design as for the dress coat but are made of white braid and embroidery. _Identification Tag._—Every officer and enlisted man of the U. S. Marine Corps on active duty is required to wear an identification tag, which consists of a round plate of white metal, one and three-eighths of an inch in diameter, suspended from the neck by a monel metal wire encased in a cotton covering. These tags are stamped as follows; for officers, full name and rank; enlisted men, full name and date of first enlistment in the Marine Corps. The tags for both officers and men also have the letters “U. S. M. C.” plainly stamped upon them. These tags are for the purpose of identification in case of death or wounds so serious as to produce unconsciousness. [Illustration: SEAL OF THE U. S.

Coast Guard are very similar to those of the Navy, and they are made of dark blue cloth for wear in cold or temperate weather and of white duck for wear in the tropics or in hot weather. A variation from this general rule is found in the case of the Keepers and surfmen on duty at the Life-Saving Stations who have uniforms of khaki or olive-drab cotton duck instead of the white uniforms of the seagoing men of the Coast Guard.

COAST GUARD Commissioned officers of the Coast Guard are required to have complete outfits of full dress, dress, evening dress, blue service dress and white service dress uniforms; the occasions for wearing the various uniforms being as follows:
