Reuel Long's experiences as an MD in the emergency rooms of Flint, Michigan, prepared him for only some of what he would see in a mobile army surgical hospital. Antiwar sentiment among the doctors in basic training at Fort Sam Houston set the tone for his tour as a general medical officer. In March 1971, the 27th MASH played a critical role treating survivors of the deadliest attack on any firebase during the Vietnam War.

Long's vivid memoir recalls the casualties he cared for during the war, including one he crossed paths with 44 years later--who in his own words describes his rehabilitation from the loss of his legs and his protesting the war from a wheelchair. An addendum gives an insider's account of the U.S. military's failure to remedy a fatal design flaw in the M16 rifle, which caused an unknown number of American casualties.
