A gold color metal and enamel device 1 1/8 inches (2.86cm) in height overall consisting of a white enamel Greek cross charged with a red disk above a maroon circle enclosing a small maroon disk, the circle having eight pointed spokes radiating from its outer edge, the upper vertical spoke surmounting the lower arm of the cross and all encircled in base by a blue scroll, the ends curving behind the horizontal arms of the cross and terminating at the upper corners inscribed "RESTORE THE STRENGTH" in gold letters.
Maroon and white are the colors used for Medical organizations. The cross, a traditional symbol for aid and assistance, alludes to the basic mission of the MEDDAC. The red disk on the white background was taken from the Japanese flag. The maroon disk circle and sight spokes refer to the elements of MEDDAC.
