H. R. McMaster

In July 2018, HarperCollins announced that it had signed a book deal with McMaster for a memoir, Battlegrounds: The Fight to Defend the Free World, to be published on April 28, 2020. The release date was later pushed back to September 15, 2020.

On May 6, 2020, Zoom Video Communications announced McMaster's appointment to its board.

McMaster is a member of the Atlantic Council's Board of Directors, and in 2019 became an Advisory Board Member of Spirit of America, a 501(c)(3) organization that supports deployed US personnel.

In February 2017, McMaster succeeded Michael Flynn as 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 to Stanford University in 2018.

In February 2018, McMaster said that it was "incontrovertible" that Russia interfered in the 2016 presidential election. McMaster, who spoke a day after a federal grand jury indicted more than a dozen Russians in connection with the interference, was addressing an international audience at the Munich Security Conference, including several Russian officials.

On March 15, 2018, it was reported that Trump had decided to dismiss McMaster from his position at a later, unspecified date. White House Press Secretary Sarah Huckabee Sanders denied the reports in a tweet, claiming nothing had changed at the National Security Council.

On March 22, 2018, McMaster was forced out as National Security Advisor after sustaining the ire of conservatives for months and disagreeing with Trump on key foreign policy strategies, including the administration's approach to Russia, North Korea, and Iran. He said in a statement that he planned to retire from the military sometime in the next few months. According to reports, the military was resistant to promoting McMaster and granting him a follow-on assignment, while McMaster was not inclined to accept the positions that were offered. Trump announced John Bolton, former U.S. Ambassador to the United Nations, as McMaster's replacement. McMaster's ouster closely followed the departures of several other high-ranking officials in the administration, including Trump's longtime assistant and communications director Hope Hicks, national economic advisor Gary Cohn, who called Trump "dumb as shit," and Secretary of State Rex Tillerson, who called him "a fucking moron." As with Tillerson's dismissal, Trump first announced McMaster's departure from the administration via a public tweet. McMaster called Trump "a dope".

McMaster's retirement ceremony was held on May 18, 2018. It took place at Joint Base Myer–Henderson Hall, and was presided over by General Mark A. Milley, the Army Chief of Staff. Among the decorations and honors McMaster received was a third award of the Army Distinguished Service Medal.

In September 2018, McMaster began work as a Bernard and Susan Liautaud Visiting Fellow at Stanford University's Freeman Spogli Institute for International Studies. He also holds the Fouad and Michelle Ajami Senior Fellowship at the Hoover Institution and serves as a lecturer in management at the University's Graduate School of Business.

On February 20, 2017, U.S. President Donald Trump nominated McMaster for National Security Advisor following the resignation of Michael T. Flynn on February 13. McMaster said at the time that he intended "to remain on active duty while he serves as national security advisor."

Because McMaster intended to remain on active duty, his official assumption of the National Security Advisor's duties and responsibilities required a United States Senate vote; lieutenant generals and generals require Senate confirmation of their rank and assignments. On March 6, 2017, the Senate Armed Services Committee voted 23–2 to recommend to the full Senate that McMaster be confirmed for reappointment at his lieutenant general rank during his service as the National Security Advisor. The committee recommendation was referred to the Senate on March 7, and the full Senate confirmed McMaster by a vote of 86–10 on March 15, 2017.

McMaster was nominated for major general on January 23, 2012, and selected to be the commander of the Army's Maneuver Center of Excellence at Fort Benning. In February 2014, Defense Secretary Chuck Hagel nominated McMaster for lieutenant general and in July 2014, McMaster pinned on his third star when he began his duties as Deputy Commanding General of the U.S. Army Training and Doctrine Command and Director of TRADOC's Army Capabilities Integration Center.

Army Chief of Staff General Martin Dempsey remarked in 2011 that McMaster was "probably our best Brigadier General." McMaster made Time' s list of the 100 most influential people in the world in April 2014. He was hailed as "the architect of the future U.S. Army" in the accompanying piece written by retired Lt. Gen. David Barno, who commanded U.S. and allied forces in Afghanistan from 2003 to 2005. "Major General Herbert Raymond McMaster might be the 21st century Army's pre-eminent warrior-thinker," Barno wrote, commenting on McMaster's "impressive command and unconventional exploits in the second Iraq war." Barno also wrote, "Recently tapped for his third star, H.R. is also the rarest of soldiers—one who has repeatedly bucked the system and survived to join its senior ranks." In 2014, retired Army Gen. Jack Keane, a former Army vice chief, commented, "It is heartening to see the Army reward such an extraordinary general officer who is a thought leader and innovator while also demonstrating sheer brilliance as a wartime brigade commander."

In August 2008, McMaster assumed duties as Director, Concept Development and Experimentation (later renamed Concept Development and Learning), in the Army Capabilities Integration Center (ARCIC) at Fort Monroe, Virginia, part of U.S. Army Training and Doctrine Command. In this position he was involved in preparing doctrine to guide the Army over the next 10 to 20 years. He was promoted on June 29, 2009. Of the 978 members of the West Point Class of 1984 commissioned into the U.S. Army, McMaster was the second promoted to General Officer. In July 2010 he was selected to be the J-5, Deputy to the Commander for Planning, at ISAF (International Security Assistance Forces) Headquarters in Kabul, Afghanistan.

From August 2007 to August 2008, McMaster was part of an "elite team of officers advising U.S. commander" General David Petraeus on counterinsurgency operations while Petraeus directed revision of the Army's Counterinsurgency Field Manual during his command of the Combined Arms Center. Petraeus and most of his team were stationed in Fort Leavenworth at the time but McMaster collaborated remotely, according to senior team member John Nagl.

In 2003 McMaster completed an Army War College research fellowship at Stanford University's Hoover Institution. In 2004, he was assigned to command the 3rd Armored Cavalry Regiment (3rd ACR). Shortly after McMaster took command the regiment deployed for its second tour in Iraq and was assigned the mission of securing the city of Tal Afar. That mission culminated in September with Operation Restoring Rights and the defeat of the city's insurgent strongholds. President George W. Bush praised this success, and the PBS show Frontline broadcast a documentary in February 2006 featuring interviews with McMaster. CBS's 60 Minutes produced a similar segment in July, and the operation was the subject of an article in the April 10, 2006, issue of The New Yorker.

McMaster passed command of the 3rd ACR on June 29, 2006, and joined the International Institute for Strategic Studies in London, as a Senior Research Associate tasked to "conduct research to identify opportunities for improved multi-national cooperation and political-military integration in the areas of counterinsurgency, counter-terrorism, and state building", and to devise "better tactics to battle terrorism."

Based on his date of rank as a colonel, McMaster was considered for promotion to brigadier general by annual Department of the Army selection boards in 2006 and 2007 but was not selected, despite his reputation as one of "the most celebrated soldiers of the Iraq War." Though the Army's rationale for whether a given officer is selected is not made public, McMaster's initial non-selection attracted considerable media attention. In late 2007, Secretary of the Army Pete Geren requested that Petraeus return from Iraq to take charge of the promotion board as a way to ensure that the best performers in combat received every consideration for advancement, resulting in McMaster's selection along with other colonels who had been identified as innovative thinkers.

Author Tim Harford has written that the pioneering tactics employed by 3rd ACR led to the first success in overcoming the Iraqi insurgency. Before 2005, tactics included staying out of dangerous urban areas except on patrols, with US forces returning to their bases each night. These patrols had little success in turning back the insurgency because local Iraqis who feared retaliation would very rarely assist in identifying them to US forces. McMaster deployed his soldiers into Tal Afar on a permanent basis, and once the local population grew confident that they weren't going to withdraw nightly, the citizens began providing information on the insurgents, enabling US forces to target and defeat them. After hearing of McMaster's counterinsurgency success in Tal Afar, Vice President Dick Cheney invited McMaster to personally brief him on the situation in Iraq and give an assessment on what changes needed to be made to American strategy.

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.

After the Gulf War, McMaster served as 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. 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 2012, became Deputy Commanding General of the Army Training and Doctrine Command.

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

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'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. 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.

Born in Philadelphia, McMaster graduated from the United States Military Academy in 1984, and later earned a Ph.D. in American history from the University of North Carolina at Chapel Hill. His Ph.D. thesis 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. During the Gulf War, McMaster served as a captain in the 2nd Cavalry Regiment, taking part in the Battle of 73 Easting.
