A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height overall consisting of an orange disc in back of a stylized white Dutch-type gable roof bearing a maroon Greek cross surmounted by a blue disc charged with a gold lion rampant as depicted on the coat of arms of the Netherlands; in base a maroon scroll lined blue folded back at each end, terminating at the base of the orange disc, and inscribed "WE SERVE TO HEAL" in gold.
The cross, a symbol of aid and assistance, represents the Hospital. The lion, the gable roof and the orange disc representing the famous native bitter orange, Curacao, allude to Curacao, Netherlands Antilles, where the predecessor organization was activated. Maroon and white are colors used for the Army Medical Department.
The distinctive unit insignia was originally approved for 356th Station Hospital on 10 January 1972. It was redesignated for the 356th Field Hospital with the description and symbolism revised effective 17 September 1993.
