FILE - In this April 9, 1969 file picture, a student leader speaks from steps of the Harvard administration building at Cambridge, Mass. as part of a protest against Reserve Officers Training Corps program at the university. Forty years ago, ROTC units disappeared from Yale, Harvard, Columbia, Stanford and other elite schools, casualties of Vietnam-era tension and academic power struggles. Now, those same schools are moving toward welcoming ROTC units back thanks to the imminent demise of "don't ask, don't tell," the policy barring gays from serving openly in the U.S. military.
