A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a maroon square with rounded corners and concave sides bearing two white heraldic fleams, the first reversed, all within a blue border surmounted at the cardinal points by a gold demi-Philippine sun of five rays and three red crosses the sun at the top and all extending slightly beyond the edge of the border.
Maroon and white are the colors of the Army Medical Department. The fleam is an ancient symbol for surgery and refers to the lineage of the Hospital. Two fleams are used to symbolize the unit's service in both World War II and Vietnam and they also simulate the unit's present numerical designation. The wavy border is used to suggest the blue Pacific where the unit served during World War II. The red cross is symbolic of aid and assistance. On the blue border the crosses represent the island campaigns of New Guinea, Bismarck Archipelago and Luzon. The demi-Philippine sun refers to the Philippine Presidential Unit Citation awarded the unit for the assault at Leyte during World War II.
The distinctive unit insignia was approved on 19 February 1970.
