DURHAM, N.H. — The first woman to lead a top-tier U.S. warfighting command urged the University of New Hampshire’s class of 2017 on Saturday to make a difference in their communities.

Air Force Gen. Lori Robinson, a 1981 graduate of the university, said during the commencement ceremony in Durham that service takes many forms, not just military service.

“No matter what your career ambitions may be, no matter what line of work you may have in mind, I’d suggest to you that as citizens of this great country, we are all called to serve … to serve our communities, our nation, our world,” she said. “Service can take many forms.”

Robinson is one of two female four-star generals in the Air Force. She currently leads the U.S. Northern Command and the North American Aerospace Defense Command.

Along with Robinson, Gov. Christopher Sununu, former state Sen. Edward Dupont Jr. and retired business executive Maureen Hurley received honorary degrees.

Plymouth State University, Saint Anselm College and Nashua Community College also held commencement ceremonies on Saturday.
