For the branch of service insignia worn by Enlisted personnel on the collars of the Service Uniform, Marine Corps regulations specify the Eagle, Globe, and Anchor from the Marine Corps seal (but without the motto ribbon) with the anchor rope continuously connected to the anchor, manufactured with a non-glossy black finish. The insignia is worn on both collars of the Service Uniform coat (the coat is manufactured with eyelets in the collars to accommodate the devices), with the eagles facing inboard and wings tips of the eagle parallel to the bottom of the coat.
Often overshadowed by the more iconic “Dress Blues” uniform, the Marine Corps Service Uniform it itself something of a classic: introduced during World War II, it has the distinction of being the oldest Service uniform still being worn (and actively produced) in the Armed Forces of the United States. Interestingly, the general public is most likely to recognize the uniform from courtroom settings: the real-life trial of Marine Corps Colonel Oliver North, and the fictional character of Colonel Nathan Jessup, portrayed by Jack Nicholson in one of his more memorable roles.
