A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height overall, consisting of a maroon Greek cross bearing at its center a black cat's head "jessant-de-lis," the fleur-de-lis of white radiating from behind the cross ten red rays, four above and six below the horizontal arm and all encircled by a continuous blue scroll, divided in four folds, the upper three inscribed "SCITE" "CITISSIME" "CERTE" in gold letters.
Maroon and white are the colors traditionally associated with the Army Medical Corps. The cross, a symbol for aid and assistance, refers to the basic mission of the Hospital. The fleur-de-lis refers to France and with the four upper red rays represents the parent unit's four campaigns in that area during World War I. The lower rays represent the six campaigns credited for service in the Philippines during World War II by that unit. Blue, white and red allude to the Philippine Presidential Unit Citation awarded during that period to the former unit. The black cat's head is a synonymous numerological reference expressive of the hospital sign. The motto, "SCITE CITISSIME CERTE" is translated as "Skillfully, Most Swiftly, Surely."
The distinctive unit insignia was originally approved for the 13th Evacuation Hospital on 26 December 1972. It was redesignated with the description and symbolism revised for the 13th Combat Support Hospital on 13 January 1993.
