From STOLEN VALOR by BG Burkett and Glenna Whitley. P.48. "Volunteers accounted for 77% of the combat deaths in Vietnam. That percentage goes up for younger men. Almost 86 percent of the nineteen-year-olds and 97 percent of eighteen-year-olds killed were volunteers."
I have however, seen the figure of 66% (volunteers) used more often than the higher figures. VFW once used 70%. Now they use 66%. Suffice to say it (the volunteer rate) was FAR higher than the rate of conscripted personnel.
