Patient flow during the Vietnam War had patients flying into McGuire Air Force Base, New Jersey. Army patients would then be moved by Air Force ambulance bus to Walson Army Hospital at the adjacent Fort Dix, where they would be further prepared for movement, typically by Army ambulance buses if they were moving to Valley Forge. In 1969, the 212th Medical Detachment (Helicopter Ambulance) was activated at Fort Meade, Maryland. One of its primary missions was to transport patients from Fort Dix, New Jersey to Valley Forge. The need was clearly there; between January 1, 1968 and September 30, 1970, 7,033 patients were moved from Dix to the Valley Forge General Hospital. The 22nd Ambulance Train was activated at Fort Dix on January 22, 1969, for the purpose of moving patients from Dix to Valley Forge, but the Penn Central Railroad informed the Army that due to the deteriorated condition of the tracks between Dix and Valley Forge, the rail line could not be used for passenger service, and the 22nd Ambulance Train never moved a single patient from the time their newly renovated train arrived on July 17, 1969, and the unit was inactivated on 20 December 1969. The 212th Medical Detachment was inactivated at Fort Meade on March 29, 1973.
