President Donald Trump has picked U.S. Army Lt. Gen. H.R. McMaster as his new national security adviser. Acting national security adviser Keith Kellogg will remain as chief of staff to the National Security Council:

“I think that combination is something very, very special,” Trump said of the pair.

McMaster is a career Army officer.

He is currently Director of the Army Capabilities Integration Center and Deputy Commanding General, Futures, U.S. Army Training and Doctrine Command.

He was previously commander of the Maneuver Center of Excellence at Ft. Benning, Georgia.

At his current job, McMaster has reviewed and analyzed ways that the U.S. and the military can act “against future threats.” Last April, he told Congress of the consequences the nation faces if lawmakers slash the defense budget:

“We are outranged and outgunned by many potential adversaries,” McMaster said. “[And] our army in the future risks being too small to secure the nation.”

Fox News continues:

He joined the Army in 1984 and distinguished himself seven years later during the Gulf War in what would become known as the Battle of 73 Easting. As captain of the 2nd Armored Cavalry Regiment’s Eagle Troop, McMaster led a force of just nine tanks that took out more than 80 Iraqi Republican Guard tanks and armored vehicles.

He is the author of the 1997 book, “Dereliction of Duty,” which criticized the U.S. government’s handling of the Vietnam War.

Last week, Michael Flynn resigned from the post after he came under fire over his contacts with Russian officials. Reports emerged that Flynn misled Vice President Mike Pence and others about talks he had with the Russian Ambassador Sergey Kislyak about sanctions former President Barack Obama passed against Russia due to interference with our election.

Pence went on Sunday talk shows to defend Flynn and insisted the advisor never spoke with the ambassador about the sanctions.
