U.S. Navy officer's combination cap, which is official regulation headgear worn by commissioned officers.
The cap features a silver spread eagle device with a federal shield over two gold crossed fouled anchors, which is the standard insignia for all officers and commissioned warrant officers.
The black visor is adorned with a single row of gold oak leaves and acorns, a decoration known as "scrambled eggs".
This specific amount of gold embroidery indicates the rank of a Commander or Captain (O-5 or O-6). Admirals have more extensive gold ornamentation.
A gold chinstrap is attached to the cap band with gold buttons.
