H. R. McMaster

Herbert Raymond McMaster (born July 24, 1962) is a retired United States Army lieutenant general who served as the 25th United States National Security Advisor from 2017 to 2018.

He is also known for his roles in the Gulf War, Operation Enduring Freedom, and Operation Iraqi Freedom.

McMaster was born in Philadelphia on July 24, 1962.

His father, Herbert McMaster Sr., was a veteran of the Korean War who retired from the Army as a lieutenant colonel.

His mother, Marie C. "Mimi" McMaster (née Curcio), was a school teacher and administrator.

He has a younger sister, Letitia.

McMaster's first assignment after commissioning was to the 2nd Armored Division at Fort Hood, where he served in a variety of platoon and company-level leadership assignments with 1st Battalion 66th Armor Regiment.

During the Gulf War, McMaster served as a captain in the 2nd Cavalry Regiment, taking part in the Battle of 73 Easting.

He attended Norwood Fontbonne Academy, graduating in 1976; and high school at Valley Forge Military Academy, graduating in 1980.

Born in Philadelphia, McMaster graduated from the United States Military Academy in 1984 and earned a Ph.D. in American history from the University of North Carolina at Chapel Hill.

His dissertation was critical of American strategy and military leadership during the Vietnam War and served as the basis for his book Dereliction of Duty, which is widely read in the United States military.

He earned a commission as a second lieutenant upon graduating from the United States Military Academy at West Point in 1984.

McMaster earned a Master of Arts and Ph.D. in American history from the University of North Carolina at Chapel Hill (UNC).

In 1989, he was assigned to the 2nd Armored Cavalry Regiment at Warner Barracks in Bamberg, Germany, where he served until 1992, including deployment to Operation Desert Storm.

During the Gulf War in 1991 McMaster was a captain commanding Eagle Troop of the 2nd Armored Cavalry Regiment at the Battle of 73 Easting.

During that battle, though significantly outnumbered and encountering the enemy by surprise as McMaster's lead tank crested a dip in the terrain, the nine tanks of his troop destroyed 28 Iraqi Republican Guard tanks without loss in 23 minutes.

McMaster was awarded the Silver Star.

The now famous battle is featured in several books about Operation Desert Storm and is widely referred to in US Army training exercises.

After the Gulf War, McMaster was a military history professor at the United States Military Academy from 1994 to 1996, became a research fellow at the Hoover Institution, a member of the Council on Foreign Relations and a Consulting Senior Fellow at the International Institute for Strategic Studies (IISS).

He held a series of staff positions in the United States Central Command.

It was also discussed in Tom Clancy's 1994 popular nonfiction book Armored Cav.

McMaster served as a military history professor at West Point from 1994 to 1996, teaching among other things the battles in which he fought.

His thesis was critical of American strategy in the Vietnam War, which was further detailed in his book Dereliction of Duty (1997).

The book explores the military's role in the policies of the Vietnam War.

It harshly criticized high-ranking officers of the era, arguing that they inadequately challenged Secretary of Defense Robert McNamara and President Lyndon B. Johnson on their Vietnam strategy.

The book examines McNamara and Johnson's staff alongside the Joint Chiefs of Staff and other high-ranking military officers, and their failure to provide a successful plan of action either to pacify a Viet Cong insurgency or to decisively defeat the North Vietnamese Army.

McMaster also details why military actions intended to indicate "resolve" or to "communicate" ultimately failed when trying to accomplish sparsely detailed, confusing, and conflicting military objectives.

The book was reportedly much read in Pentagon circles and included in military reading lists.

He graduated from the United States Army Command and General Staff College in 1999.

McMaster commanded 1st Squadron, 4th Cavalry Regiment from 1999 to 2002, and then took a series of staff positions at U.S. Central Command (USCENTCOM), including planning and operations roles in Iraq.

In his next job, as lieutenant colonel and later colonel, McMaster worked on the staff of USCENTCOM as executive officer to Deputy Commander Lieutenant General John Abizaid.

When Abizaid received four-star rank and became Central Command's head, McMaster served as Director, Commander's Advisory Group (CAG), described as the command's brain trust.

In 2003 McMaster completed an Army War College research fellowship at Stanford University's Hoover Institution.

In 2004, he took command of the 3rd Cavalry Regiment and fought the Iraqi insurgency in Tal Afar.

He became a top counterinsurgency advisor to General David Petraeus before serving as the Director of the Army Capabilities Integration Center.

He also served as the Deputy to the Commander for Planning of the International Security Assistance Force in Afghanistan and, in 2014, became Deputy Commanding General of the Army Training and Doctrine Command.

In February 2017, McMaster succeeded Michael Flynn as President Donald Trump's National Security Advisor.

He remained on active duty as a lieutenant general while serving as National Security Advisor, and retired in May 2018.

McMaster resigned as National Security Advisor on March 22, 2018, effective April 9, and accepted an academic appointment at Stanford University in 2018.

McMaster is the Fouad and Michelle Ajami Senior Fellow at the Hoover Institution, the Bernard and Susan Liautaud Visiting Fellow at the Freeman Spogli Institute for International Studies and a lecturer in management at the Stanford Graduate School of Business.
