A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height overall consisting of a gold eight-rayed sun bearing a maroon Greek cross, all in front of gold rays issuing from the center of the sun and terminating above white-capped gold mountain peaks in base; flanking the sun on the left, a palm tree with gold trunk and green fronds, and on the right a white fleur-de-lis; all enclosed by a continuous maroon scroll arched at top and inscribed "GO AND DO," the scroll extending in back of the palm tree and fleur-de-lis at the sides and inscribed in base "THOU LIKEWISE," all letters gold.
Maroon and white are the colors used for the Army Medical Department. The eight-rayed sun from the flag of the Philippine President commemorates the hospital's service in World War II, for which it was awarded the Philippine Presidential Unit Citation, the palm tree referring to the New Guinea and Luzon campaigns. The fleur-de-lis indicates the unit's service in World War I. The cross, a symbol of aid and assistance, signifies the historical organization of the unit at Good Samaritan Hospital, Los Angeles, California. The gold rays in the background, which allude both to sunny California and to healing, and the motto from the story of the "Good Samaritan," also refer to the origin and function of the hospital. The snow-capped mountains allude to the unit's 1947 activation in Utah.
