I also found this:

"Project 100,000," a Great Society program launched in 1966, attempted to enhance the opportunities of underprivileged youths from poverty-stricken urban areas by offering more lenient military entrance requirements. It largely failed. Although more than 350,000 men enlisted under Project 100,000 during the remainder of the war, 41 percent were African American and 40 percent drew combat assignments. Casualty rates among these soldiers were twice those of other entry categories. Few Project 100,000 inductees received training that would aid their military advancement or create better opportunities for civilian life.

None of the recruits I was involved with got in under this program. I think it must have been used more in the 1960s since I never was informed of it.
