On a white shield within a 1/8 inch (.32 cm) red border, a red saltire surmounted by a yellow sun with 5 pointed and 5 wavy alternating rays. The overall dimensions are 3 inches (7.62 cm) in height and 2 1/4 inches (5.72 cm) in width.
The white ground with the red saltire was suggested by the state flag of Florida. The sun alludes to the Sunshine State, the sobriquet by which Florida is known. The sun also refers to the Command Headquarters and the 5 pointed and 5 wavy rays to the numerical designation 55.
The shoulder sleeve insignia was approved on 20 November 1964. (TIOH Dwg. No. A-1-398)
