A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height overall consisting of a red Greek cross surmounted by a gold fleam on top of white heraldic potent pointed at the foot with point extending over a continuous maroon scroll arched around top and base, doubled blue behind the lateral arms of the Greek cross, inscribed "AID" at the top, "CONSERVE" left of the potent and "SUPPORT" on the right, all in gold.
The red cross, symbol for aid and assistance, and the fleam, ancient symbol for a lancet, represent both the unit and the wide range of the unit's medical care and services. The potent implies air mobility and speed in the collection, treatment and evacuation of wounded and other casualties from combat and advanced areas. The pointed foot alludes to a tent peg, a tool frequently used in pitching temporary emergency hospitalization for all classes of patients including the medically austere. Maroon and white are the colors used for the Army Medical Department and blue and gold refer to Pennsylvania, the unit's present location.
The distinctive unit insignia was approved on 3 December 1975.
