An example of the Nixon Doctrine is the United States' approach to its allies during the Vietnam War. Announced by President Richard Nixon in 1969, the doctrine stated that while the U.S. would support its allies in their defense, those countries would be responsible for their own military defense. This shift aimed to reduce American ground troop involvement while still providing military and economic assistance, exemplified by the U.S. support for South Vietnam as it fought against North Vietnamese forces.

The United States began sending troops to Vietnam in a significant capacity in March 1965, when President Lyndon B. Johnson ordered the deployment of combat forces to support the South Vietnamese government against the communist Viet Cong. However, U.S. involvement in Vietnam had started earlier, with military advisors and support personnel being sent as early as the late 1950s. The troop presence escalated throughout the 1960s, peaking in 1969.

It depends on when in 1973 you're talking about. On March 23, 1973, as a result of the Paris Peace Accords, the US withdrew its remaining 2500 troops. The Department of Defense lists 1973 troop levels (presumably after the aforementioned troop withdrawal) at 50 US troops and 111000 South Vietnamese troops.
The peak US troop strength in Vietnam, of 543,482, was achieved on April 30, 1969.
