A gold color metal and enamel device 1 3/16 inches (3.02 cm) in width overall consisting of a gold circular background with incised radiating lines bearing a dark red (maroon) Greek cross surmounted on a red (scarlet) Greek cross bearing a white star above a white domed tower with an ogee arch over a red (scarlet) and blue (ultramarine) Taeguk, all enclosed by a red (maroon) circular scroll inscribed "RESUSCITATE AND CONSERVE" in gold letters.
The white domed tower alludes to the Taj Mahal and symbolizes the unit's service in India. The Meritorious Unit Citation, embroidered Korea, is represented by the Taeguk, a symbol of South Korea. The star was suggested by the flag of Burma and here represents combat service in Burma. The rayed background stands for the hope and healing offered by the Hospital in the Far East (China). The red cross is a symbol of hospital units, while maroon is a color used by the Medical Department.
The distinctive unit insignia was originally approved for the 46th Surgical Hospital on 6 June 1969. It was redesignated for the 46th Combat Support Hospital on 6 August 1973.
