The composition of U.S. troops in Vietnam closely mirrored the national demographics of the time. A significant majority, 88.4%, were Caucasian, while African-Americans, who made up about 11% of the U.S. population according to the 1970 census, represented 10.6% of the forces deployed.

Other races accounted for 1% of the military personnel. Notably, the socio-economic background of these soldiers predominantly hailed from working-class families, comprising 76% of those who served. This period also marked a shift in the educational attainment of enlisted men, with most troops having completed high school, a notable increase from previous conflicts.
