A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a red annulet centered with a yellow disc elevated and behind the upper vertical arm of a maroon Greek cross on a white background and all above and between a blue scroll, the ends curving upwards and inwards and terminating one end on the right frontal plane of the annulet and the other end behind the annulet inscribed "PROFESSIONAL READINESS" in gold letters.
Maroon and white are the colors traditionally associated with the Medical Department. The cross, a traditional symbol for aid and assistance, refers to the basic mission of the Hospital. The yellow disc represents the circle of perfection and the red band, or annulet, refers to continuity and courage. The red annulet with the yellow disc further simulates the device from the flag of the state of Colorado, home area of the Hospital.
The distinctive unit insignia was originally approved for the 147th U.S. Army Hospital on 11 June 1971. It was redesignated for the 147th Medical Hospital, Colorado Army National Guard on 25 April 1973. The insignia was redesignated, with description and symbolism revised for the 147th Combat Support Hospital on 3 May 1989.
