The Viet Cong bombed the Brinks Hotel in Saigon, killing two U.S. Army officers and raising fears of an escalation of the Vietnam War.

The Viet Cong (VC) was an epithet and umbrella term to refer to the communist-driven armed movement and united front organization in South Vietnam. It was formally organized as and led by the National Liberation Front of South Vietnam, and conducted military operations under the name of the Liberation Army of South Vietnam (LASV). The movement fought under the direction of North Vietnam against the South Vietnamese and United States governments during the Vietnam War. The organization had both guerrilla and regular army units, as well as a network of cadres who organized and mobilized peasants in the territory the VC controlled. During the war, communist fighters and some anti-war activists claimed that the VC was an insurgency indigenous to the South that represented the legitimate rights of people in South Vietnam, while the U.S. and South Vietnamese governments portrayed the group as a tool of North Vietnam. It was later conceded by the modern Vietnamese communist leadership that the movement was actually under the North Vietnamese political and military leadership, aiming to unify Vietnam under a single banner.

The Brinks Hotel in Saigon, also known as the Brink Bachelor Officers Quarters (BOQ), was bombed by the Vietcong on the evening of 24 December 1964, during the Vietnam War. Two Vietcong operatives detonated a car bomb underneath the hotel, which housed United States Army officers. The explosion killed two Americans, an officer and an NCO, and injured approximately 60, including military personnel and Vietnamese civilians.

Ho Chi Minh City, also known as Saigon, is the most populous city in Vietnam with a population of 14,002,598 in 2025.

The United States Army (USA) is the primary land service branch of the United States Department of Defense. It is designated as the Army of the United States in the United States Constitution. It operates under the authority, direction, and control of the United States secretary of defense. It is one of the six armed forces and one of the eight uniformed services of the United States. The Army is the most senior branch in order of precedence amongst the armed services. It has its roots in the Continental Army, formed on 14 June 1775 to fight against the British for independence during the American Revolutionary War (1775–1783). After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.
