U.S. Army Public Health Command (USAPHC) has the mission to promote health and prevent disease, injury, and disability of Soldiers and military retirees, their families, and Department of the Army civilian employees. The Command also works to assure effective execution of full spectrum veterinary service for Army and Department of Defense Veterinary missions. USAPHC’s public health responsibilities are far-reaching, extending beyond humans to include animals and the environment, where some of the causes of disease, injury, and disability in people originate. Avian flu, unsafe drinking water, food that has spoiled or has not been safely processed or prepared, ineffective sanitation measures in the aftermath of natural disaster, exposure to industrial chemicals, mold in the workplace are a few examples of the health threats stemming from animals or the environment that Army public health professionals address.

The 1st Army and the 9th Army Medical Laboratories are based at Aberdeen Proving Ground. These organizations deploy world-wide to perform surveillance, confirmatory analytical laboratory testing and health hazard assessments of environmental, occupational, endemic and chemical, biological, radiological, nuclear or explosive threats in support of force protection and WMD missions.

The Medical Institute for Chemical Defense (MRICD) is another organization at APG with medical research as part of its mission area. The Institute for Chemical Defense focuses on basic and applied research in the pharmacology, physiology, toxicology, pathology and biochemistry of chemical agents, and medical countermeasures.
