A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a maroon isosceles triangle with two wavy gold bars in base in back of a red Greek cross bearing a white tower between three gold ermine spots, the foot of the cross coinciding with the base of the triangle.

Maroon and white are the colors used for the Army Medical Department and a red cross is symbolic of aid.  The triangle and wavy bars simulate a mountainous island and represent the Aleutian Island campaign in which the unit participated during World War II.  An ermine spot is associated with Europe, and three are used to refer to the Northern France, Rhineland and Central Europe campaigns, the tower, taken from the arms of Antwerp, denoting the unit's medical service during the V-1 and V-2 bombings for which the organization was cited in the Order of the Day and decorated.

The distinctive unit insignia was approved on 15 June 1971.
