  1. In January 2016, he served as the Group’s Chief of Staff until June 2016 when he assumed command of 2d Marine Logistics Group.? Um, typo? O’Hora’s bio seems to be mixed with someone else… like the commander of 2nd MLG?

  2. My goodness. With all of his work and awards he sounds stellar to me. What in the name of God is expected of him? He has dedicated his life to the service of our USA. With his qualifications and experience he could outdo most of what we depend on in DC. How could he be unable to serve as a leader? My prayers and good thoughts are with him and his family.
