Walter Reed Army Institute of Research
The Walter Reed Army Institute of Research (WRAIR) is the largest biomedical research facility administered by the U.S. Department of Defense (DoD). The institute is centered at the Forest Glen Annex, in the Forest Glen Park part of the unincorporated Silver Spring urban area in Maryland just north of Washington, DC, but it is a subordinate unit of the U.S. Army Medical Research and Development Command (USAMRDC), headquartered at nearby Fort Detrick, Maryland.
