The 54-year-old McMaster replaces retired Army Lt. Gen. Michael Flynn as the president's national security adviser. Flynn was forced to resign after lying about talking to Russia before he officially took the NSA post about recently imposed sanctions.
McMaster is a career army officer and director of the Army Capabilities Integration Center.
He joined the U.S. Army in 1984 and distinguished himself seven years later during the Gulf War in what would become known as the Battle of 73 Easting.
He is the author of the 1997 book, "Dereliction of Duty," which criticized the U.S. government's handling of the Vietnam War.
In his latest role, McMaster was tasked with gauging the U.S, military capability against future threats. When he addressed lawmakers in April of last year, he warned that years of military cuts have left the U.S. vulnerable.
