Above the shield is the crest, with a rooster, also a symbol of Aesculapius and ancient medicine, moving forward (to the viewer's left), but looking backwards. This symbolizes the department's motto, Experientia et Progressus, Latin for Experience and Progress. The Medical Department provides world-class medical care, grounded in the centuries of medical experience passed down to each successive generation, while constantly moving forward to improve the quality of the care we provide, in service to the nation.
