Project 100,000 (also McNamara's 100,000) was a 1960s program by the United States Department of Defense (DoD) to recruit soldiers that would previously have been below military mental or medical standards. Project 100,000 was initiated by Defense Secretary Robert McNamara in October 1966 to meet the escalating manpower requirements during American involvement in the Vietnam War and ended in December 1971.
At various times in its history, the United States military has recruited people who measured below specific mental and medical standards. Those who scored in certain lower percentiles of mental aptitude tests were admitted into service during World War II, though this experience eventually led to a legal floor of IQ 80 to enlist. Another instance occurred in the 1980s due to a misnormed Armed Services Vocational Aptitude Battery.
Promoted as a response to President Lyndon B. Johnson's War on Poverty by giving training and opportunity to the uneducated and poor, the recruited men were classified as "New Standards Men" (or, informally and pejoratively, as the "Moron Corps"). They had scored in Category IV of the Armed Forces Qualification Test, which placed them in the 10-30 percentile range. The number of soldiers reportedly recruited through the program varies, from more than 320,000 to 354,000, which included both voluntary enlistees and draftees (54% and 46%, respectively). Entrance requirements were loosened, but all the Project 100,000 men were sent through normal training programs with other recruits, and performance standards thus were the same for everyone.
Project 100,000 soldiers included those unable to speak English, of low mental aptitude, with minor physical impairments, as well as those who were slightly overweight or underweight, among other categories. They also included a special category—a control group of normal soldiers. Each of the different categories was identified in their official personnel records with a large red letter stamped on the first page of their enlistment contract. Human resources offices had to prepare reports on them, to be submitted monthly to the Department of the Army. The monthly reports did not include the identity of the soldiers.
While the project was promoted as a response to President Lyndon Johnson's War on Poverty, it has been an object of criticism. Regarding the consequences of the program, a 1989 study sponsored by the DoD concluded: 
Comparisons between Project 100,000 participants and their nonveteran peers showed that, in terms of employment status, educational achievement, and income, nonveterans appeared better off. Veterans were more likely to be unemployed and to have a significantly lower level of education. Income differences ranged from $5,000 [to] $7,000, in favor of nonveterans. Veterans were more likely to have been divorced.
A 1995 review of McNamara's book In Retrospect: The Tragedy and Lessons of Vietnam in the Washington Monthly severely criticized the project, writing that "the program offered a one-way ticket to Vietnam, where these men fought and died in disproportionate numbers...the men of the 'Moron Corps' provided the necessary cannon fodder to help evade the political horror of dropping student deferments or calling up the reserves, which were sanctuaries for the lily-white."
Project 100,000 was highlighted in a 2006 op-ed in The New York Times in which former Wesleyan assistant professor and then Tufts assistant professor Kelly M. Greenhill, writing in the context of a contemporary recruitment shortfall, concluded that "Project 100,000 was a failed experiment. It proved to be a distraction for the military and of little benefit to the men it was created to help." For the reason that veterans from the project fared worse in civilian life than their nonveteran peers, Greenhill hypothesized it might be related to the psychological consequences of combat or unpreparedness for the post-military transition.
