McMichael sits on the steering committee of the National Symposium for the Needs of Young Veterans, hosted by AMVETS.[7]
In 2003, the Boys & Girls Clubs of America citing that "the Sergeant Major [had] come a long way from segregated Hot Springs, where the Club was the only colorblind place to play," named McMichael to its "Alumni Hall of Fame." McMichael commented, "The Club gave me those things I use today in the Marine Corps . . . You made a difference in one child’s life." McMichael credits the Club, which he joined at age 9, with giving him a vision of what the world should and could be.
In 2008, McMichael's memoirs were published under the title LEADERSHIP: Achieving Life-Changing Success From Within.[8]
