wear combination covers; their cap device is a golden representation of the Coast Guard emblem. Coast Guard chief petty officers' cap devices match those of the Navy, albeit with a shield on the front of the fouled anchor; like Navy chiefs, their cap devices are enlarged renderings of the rank insignia worn on their collars. Coast Guard officers' cap device is an eagle with wings outstretched, above an anchor grasped horizontally in its talons. United States Marine Corps In the United States Marine Corps, these caps, bearing a cap badge of the Corps' Eagle, Globe, and Anchor (EGA) device, are worn in two forms. For blue dress uniforms, the cap is white with a gloss black visor. The enlisted version features a black chin strap and is worn with an all-gold EGA device, while the officer version features a gold and scarlet chinstrap and a gold and silver EGA device. In addition, officers wear a lace cross on the top, called the quatrefoil, a traditional mark of distinction enabling sharpshooters aboard ships to identify friendly officers from foes. For the green service uniforms, an olive drab combination cap is available; the EGA device and the chin strap are black for all ranks. In both cases, field grade officers (majors, lieutenant colonels and colonels) have gold oak leaf motifs on the visor, similar to those worn by navy commanders and captains, while general officers' caps have a different, larger oak leaf motif on the visor. Additionally the blue dress cap of the Commandant of the Marine Corps (as well as the Chairman of the Joint Chiefs of Staff if it is also a Marine) adds an additional gold oak leaf motif to the front of the band. In the Marine Corps, the combination cap is commonly referred to as the "barracks cover", and the particular versions are referred as the dress cap or service cap in Marine Corps Orders. United States Navy In the United States Navy, midshipmen, chief petty officers, and commissioned officers wear combination covers, but there are differences between the three types. In general, the cap has a rigid framed crown with a cloth cover, a black hatband that extends to a semicircle on the grant to support a badge device, a glossy black visor, and a chinstrap secured by two gold colored buttons that match the buttons of the wearer's service dress uniform.
