A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of two embowed serpents facing outwards to the right and left, their tails enclosing a white five-pointed star all below a red Greek cross bearing a gold anchor all beneath a green scroll arched from the heads of the serpents, bearing the inscription "ONE BETTER TO SERVE" in gold letters.
Maroon and white are the colors used for the Army Medical Department. Green, the color of the coat of the "ancient physician," relates to the star on the flag of Burma and to the star of India, the campaign in which the unit participated during World War II. The star also signifies achievement and represents the unit's training performance. The red cross is a symbol for aid, and the dual serpents were suggested by the Medical insignia. The anchor, taken from the arms of Rhode Island, suggests the homesite of the Hospital.
The distinctive unit insignia was originally approved for the 455th General Hospital on 21 May 1970. It was redesignated for the 455th Field Hospital with the description and symbolism revised effective 17 September 1993.
