A green cross is used on the Distinctive Unit Insignia of the U.S. Army Medical Department Activity (MEDDAC), Fort Leavenworth to denote the installation’s history as a pioneer Army post that was a crossroad of the early West. On the cross, a stylized tropical medical tent is an allusion to Brigadier General Edward L. Munson, who developed an eponymous Medical Tent for use in the field and was the inspiration for the original name of the Fort’s Hospital, which is currently known as the Munson Army Health Center.
Also responsible for developing a system of field training for Medical Department officers and enlisted personnel, Munson’s service in the Medico-Military service in the Philippine Islands, Japan, and other Far-East assignments is commemorated with the rising sunburst behind the green cross; the sunburst is also a nod to the organization’s home state of Kansas, the “Sunflower State.” “CONSTANT DEDICATED CARE” is the unit motto.
The Distinctive Unit Insignia of the MEDDAC, Fort Leavenworth was originally approved for the U.S. Munson Army Hospital on 25 November 1969. It was redesignated on 4 September 1973 for the U.S. Army Medical Department Activity, Fort Leavenworth.

Also known as a unit crest or DUI, a Distinctive Unit Insignia is worn by all Soldiers (except General Officers) in units that have been authorized to be issued the device. It is worn centered on the shoulder loops of the Army Green Service Uniform (AGSU) and the blue Army Service Uniform (ASU, Enlisted only) with the base of the insignia toward the outside shoulder seam. DUIs are not worn on the Dress variations of either uniform, however. More guidance on wear of the DUI is found in DA Pamphlet 670-1, Section 21-22, "Distinctive unit insignia" and 21–3(d) and (e), "Beret" and "Garrison Cap," respectively.
