99TH COMBAT SUPPORT HOSPITAL
Distinctive Unit Insignia
A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a green equilateral triangle with a gold demi-Philippine sun rising from base and a red Greek cross with the upper vertical arm overlapping the disc of the sun and upper edge of the lateral arms coinciding with the lower edge of the triangle, all above a maroon scroll arced from the base of the triangle and inscribed "AID AND ASSIST" in gold letters; the enclosed area between the triangle and scroll of white enamel.
Maroon and white are the colors used for the Army Medical Department and the red cross refers to the mission and the motto. The triangle simulates the shape of an island and alludes to New Guinea and the Philippines where the unit participated in two campaigns during World War II. The color red denotes the Meritorious Unit Commendation Award for Mindanao and the sun refers to the Philippine Presidential Unit Citation for the Philippine Liberation.
The distinctive unit insignia was originally approved for the 99th Evacuation Hospital on 8 February 1974. It was redesignated for the 99th Combat Support Hospital on 20 January 1975.
