In the United States Army soldiers of ranks Specialist and below are not authorized to wear a combination cap and may only wear a beret with the blue service uniform. The combination cap for the blue service and blue dress uniforms of noncommissioned officers (Corporal and above) has a golden stripe on top of the cap band, black chinstrap; the device is the United States' coat of arms in front of a gold disk (the exception is the Sergeant Major of the Army whose device is a gold-colored rendering of the U.S coat of arms surrounded by a gold-coloured wreath). The version for warrant officers and company-grade officers (second lieutenants, first lieutenants, & captains) has a cap band with the branch-of-service color between two golden stripes, and a gold-colored chinstrap. Field-grade officers O-4 and Above (major, lieutenant colonel, and colonel) have oak leaves known unofficially as "scrambled eggs" on the visor. General officers' caps are similar to those of field-grade officers, but the cap band is dark blue and embroidered with gold oak leaf motifs. Warrant officers' cap device and all commissioned officers' cap device is a gold-color rendering of the United States' coat of arms, larger than that of soldiers and lacking the golden disk backing.
