McMaster, 54, is a West Point graduate known as “H.R.,” with a PhD in U.S. history from the University of North Carolina at Chapel Hill. He was listed as one of Time magazine’s 100 most influential people in 2014, partly because of his willingness to buck the system.
A combat veteran, he gained renown in the first Gulf War – and was awarded a Silver Star – after he commanded a small troop of the U.S. 2nd Army Cavalry Regiment that destroyed a much larger Iraqi Republican Guard force in 1991 in a place called 73 Easting, for its map coordinates, in what many consider the biggest tank battle since World War Two.
As one fellow officer put it, referring to Trump’s inner circle of aides and speaking on condition of anonymity, the Trump White House “has its own Republican Guard, which may be harder for him to deal with than the Iraqis were.” The Iraqi Republican Guard was the elite military force of ousted dictator Saddam Hussein.
McMaster’s fame grew after his 1997 book “Dereliction of Duty” criticized the country’s military and political leadership for poor leadership during the Vietnam War.
