McMaster serves at Stanford University as the Fouad and Michelle Ajami Senior Fellow at the Hoover Institution, the Susan and Bernard Liautaud Fellow at the Freeman Spogli Institute, and as lecturer at the Graduate School of Business.He served as a commissioned officer in the United States Army for 34 years until his retirement, in 2018, as the 26th Assistant to the President for National Security Affairs. The young tank captain who in 1991 won fame for outfighting a far larger Iraqi force at the Battle of 73 Easting is the intellectual voice of the Army, to whom the service turns when it needs to examine policy, doctrine and professionalism. McMaster’s outspoken style almost derailed his career when he was passed over for promotion to brigadier general. But having been part of the team that helped Gen. David Petraeus rewrite the book on counterinsurgency in 2006, he has found support for his vision, tolerance for his candor, and a place among the Army’s small cadre of rising stars.
