Context: The Forest Glen Annex is a 136 acre U.S. Army installation in the Forest Glen neighborhood of Silver Spring, Maryland, USA.  It is situated between Brookville Road and Linden Lane.  Since 1999, the Annex has been the site of the Walter Reed Army Institute of Research (WRAIR) and the Naval Medical Research Center (NMRC), along with smaller units.  In addition to the large research laboratories located in the Annex’s "Daniel K. Inouye Building" (Building 503), the post includes a commissary, a child care center, and a Fisher House.  There are also football and baseball fields, and picnicing facilities.  In 2011, in accordance with the most recent Base Realignment and Closure (BRAC) recommendations, the Forest Glen Annex became home to the National Museum of Health and Medicine (NMHM) as well as a "Joint Center of Excellence in Infectious Disease Research."  The former post exchange was repurposed as office space and a new Army and Air Force Exchange Service (AAFES) was opened at the Walter Reed National Military Medical Center. The Walter Reed Health Care System (WRHCS) is the United States Army's comprehensive and integrated health care delivery system for the National Capital Region.  It provides the full range of health care to members of the military and their families as well as members of the federal government.  The WRHCS encompasses the Walter Reed Army Medical Center and seven other Army hospitals and health care clinics in Maryland, Pennsylvania, and Virginia. Vassar Brother Medical Center (locally known as Vassar Hospital or VBMC) is a major medical facility located in the city of Poughkeepsie, New York that is a member of the Health Quest network, a nonprofit family of hospitals and healthcare centers in the Hudson Valley area.  VBMC is one of two major medical centers located in Dutchess County, New York, the other being Mid-Hudson Regional Hospital of Westchester Medical Center.  The hospital was first incorporated in 1882 under the name Vassar Brothers Hospital, following contributions made by John Guy Vassar following the death of his brother.  The hospital opened its doors in 1887, and initially had 40 beds divided up into four wards, each containing ten beds.  At the time the hospital opened it also contained a labor and delivery ward, a children's ward, a nursery, three private rooms, and two isolation rooms.  Several major renovations occurred in 1983, 1991, and 2001; adding critical care areas, a new operating and delivery wing, and a cancer care center, respectively.  In 2002 Vassar Brothers Hospital officially became Vassar Brothers Medical Center.  In September 2016, VBMC announced a new $500 million expansion which would almost double the number of available rooms.  Construction on the expansion is expected to be completed in 2019. The Walter Reed Army Medical Center neglect scandal refers to a series of allegations of unsatisfactory conditions, treatment of patients, and management at the Walter Reed Army Medical Center (WRAMC) in Washington, D.C. culminating in two articles published by "The Washington Post" in February 2007.  Several cases of patient neglect and shoddy living conditions were reported as early as 2004.  "Soldiers suffering from traumatic brain injuries or stress disorders, others with amputated limbs, have languished for weeks and months on end in vermin-infested quarters waiting for a decision on their military status and a ruling on the level of benefits they will receive if they are discharged and transferred to the civilian-run Veterans Administration (VA) healthcare system."  When the scandal broke, soldiers were pressured to keep quiet and punished with daily inspections for speaking to the press.  Significant public and media attention was generated, which in turn prompted a number of congressional and executive actions, including resignations of several high-ranking officers.  CPT Micheal Dake did not implement any changes that rectified the disrepair of Building 18.  The initiatives of the following Command Team lead to Building 18 being repaired and made livable.  It was when the building was left dormat during the summer that mold became a problem. The Walter Reed Army Medical Center (WRAMC) — known as Walter Reed General Hospital (WRGH) until 1951 — was the U.S. Army's flagship medical center from 1909 to 2011.  Located on 113 acre in Washington, D.C., it served more than 150,000 active and retired personnel from all branches of the military.  The center was named after Major Walter Reed (1851–1902), an army physician who led the team that confirmed that yellow fever is transmitted by mosquitoes rather than direct contact. Major General George W. Weightman was a U.S. Army Family Medicine physician who was commander of the North Atlantic Regional Medical Command and Walter Reed Army Medical Center (WRAMC).  He was relieved of his WRAMC command on March 1, 2007, in the wake of the Walter Reed Army Medical Center neglect scandal.  He took command of the U.S. Army Medical Research and Materiel Command in November 2007 and retired from active duty on 31 March 2009. Building 40, Army Medical School is a Georgian revival structure in the Walter Reed Army Medical Center complex in northern Washington, D.C., USA.  It was built between 1922 and 1932 to house the Army Medical School, which became the Army Medical Center in 1923 when it — under the name “Medical Department Professional Service School” (MDPSS) — combined with the Walter Reed General Hospital.  The MDPSS ultimately became the Walter Reed Army Institute of Research, which occupied Building 40 from 1953 to 1999.  It comprises four wings, known as the Craig (1924), Sternberg and Vedder (1932), and Siler (1962) Pavilions and is situated at 14th and Dahlia Streets. Major General (Ret.)  Kevin C. Kiley (born October 18, 1950) was the 41st Surgeon General of the United States Army and commander of the U.S. Army Medical Command, Fort Sam Houston, Texas.  He was commander of Walter Reed Army Medical Center and North Atlantic Regional Medical Command twice, from 2002 to 2004, and as acting commander, March 1–2, 2007.  He submitted his request to retire from the U.S. Army on March 11, 2007, in the wake of the Walter Reed Army Medical Center neglect scandal, and was removed from his nominative billet as a Lieutenant General.  Pending retirement, he was assigned to a temporary billet at the General Officer Management Office at the Pentagon in the grade Major General.  His retirement in the grade of Major General was subsequently approved. Eric B. Schoomaker (born September 15, 1948) is a former United States Army lieutenant general who served as the 42nd Surgeon General of the United States Army and Commanding General, United States Army Medical Command, and a practicing hematologist.

Housing over 8,000 patients at its peak in the 1950s, the hospital at one point had a fully functioning medical-surgical unit, a school of nursing, and accredited internships and psychiatric residencies.  Its campus was designated a National Historic Landmark in 1990.
