It is headquartered at Fort Sam Houston, San Antonio, Texas, which hosts the AMEDD Center and School (AMEDDC&S).

Large numbers of AMEDD senior leaders can also be found in the Washington D.C. area, divided between the Pentagon and the Walter Reed National Military Medical Center (WRNMMC).

The Academy of Health Sciences, within the AMEDDC&S, provides training to the officers and enlisted service members of the AMEDD.

The ancient Greeks believed that the rooster's crowing at dawn drove away the evil disease-spreading demons from the temples so that it could be a place of healing.

The torse (twisted rope) below the rooster shows alternating blue and silver colors which were representative of the Army in 1818.

This is in great measure a result of veterinary inspection of subsistence in the United States as well as the approval of safe food sources around the world.

Army veterinarians ensure the health of military working dogs and assist with host-nation related animal emergencies.

Veterinary staff advisors also play key roles regarding issues involving chemical and biological defense.

[9] In the United States, military veterinary supervision of operational ration assembly plants, supply and distribution points, ports of debarkation, and other types of subsistence operations are critical to ensuring safe, wholesome food for our Soldiers, Sailors, Airmen, Marines, and their family members.

The large segment of the Veterinary Corps involved in Medical Research and Development missions contribute immeasurably to the overall military effort.

Medical Service Corps officers serve as commanders of field medical units in garrison and combat environments, and provide healthcare to patients as psychologists (PhD, PsyD), social workers (MSW with state license), optometrists, pharmacist, podiatrists, and audiologists.

The Medical Service Corps also functions as a transitional branch, encompassing commissioned medical, dental, and veterinary students who have not completed their training through the Uniformed Services University of the Health Sciences (USUHS) or the Health Professions Scholarship Program (HPSP).
