Marvin also authored four books, "Guardian Down," "Breakaway Days," "Sports and the Heroic," and "World Without End."

Marvin was a devoted husband to Gail, loving father to Michael, Michelle and Stephanie, proud grandfather to Will, Chris, Cate-Elise, Michael, and Matthew. He was a loyal friend to his sons-in-law Marcus and Jeffrey, as well as to his extended family and many others. He was known for his thoughtful wisdom, philosophical insights, sharp mind, dry wit, and deep love of history, justice, and country. Whether leading troops or mentoring young people, Marvin left a lasting impression on all who knew him.
