A gold color metal and enamel device 1 1/4 inches (3.18 cm) in height overall consisting of a semi-circular yellow disc (the sun) behind five blue (ultramarine) mountain peaks, the central peaks snow-capped (white) and forming below a white Greek cross bearing a scarlet Greek cross, superimposed, above and below the vertical arm of the cross, a gold sword of sacrifice, point down, in base a green background, all between a maroon scroll folded into three sections and inscribed "COMFORT HEAL RELIEVE" in gold letters.
The cross, symbolic of aid and assistance, represents the Fitzsimons Army Medical Center. The single sword of sacrifice, with point down, alludes to First Lieutenant William Thomas Fitzsimons, MC, U.S. Army, the first American officer killed by enemy action during World War I after whom the Center is named. The stylized snow-capped mountains symbolize the Colorado Rockies and the location of the Center at Denver. The golden sun ball was suggested by the State Flag of Colorado and alludes to the healing and health producing rays of the sun; the green base represents the green plains and mountain slopes of the area. Maroon and white are colors used by the Medical Department.
The distinctive unit insignia was originally approved for Fitzsimons General Hospital on 20 January 1971. The insignia was redesignated for Fitzsimons Army Medical Center on 15 August 1973.
