The weapons the US Government provided. In the early years of the war the were furnished WWII era weapons, later, were provided the same mat
The full might of the US military minus nuclear weapons.
The US DID change it's tactics in Vietnam. The war went FROM a guerrilla war TO a conventional war (tanks and B-52 bombers). Had President Kennedy lived, Vietnam very well could have been fought by the USN SEALS and USA Special Forces (Green Berets). Fighting fire with fire. When Kennedy died, the WWII Generals took over; and Vietnam went WWII style (jets fighting jets, tanks fighting tanks, etc.).
There were five presidents in total . Eisenhower, Kennedy, Johnson Nixon and Ford. The US participation began with Eisenhower in 1954, We left in 1974. All but Ford escalated the US involvement. Eisenhower started it, Kennedy sent in the SEALS and Green Berets, Johnson sent in regulars and commenced bombing North Vietnam. Nixon invaded Cambodia and Laos and B52'd Hanoi to the peace talks. Ford pulled everybody out.
Special Forces (Green Berets) were sent to Vietnam by President Kennedy in the early 1960's. REGULAR US ground troops were sent in 1965.
The last of the US GROUND TROOPS were pulled out. Conventional forces only, NOT the advisors, Special Forces (Green Berets), etc.
There are roughly 4500 estimated Green Beret soldiers. it is said that the Green Berets make up less than 1% of the US Army's population.
The US joined the Vietnam War in 1960 or 1955because there was a civil war between North Vietnam and South Vietnam, and the US was good friends with South Vietnam's goverment, so they helped out.
The US have Delta Force, Rangers and Green Berets.
