when did the us have a standing army
History of the United States Army When the American Revolutionary War began in April 1775, the colonial revolutionaries did not have an army. Previously, each colony had relied upon the militia, made up of part-time civilian-soldiers. The initial orders from Congress authorized ten companies of riflemen. The first full regiment of Regular Army infantry, the 3rd Infantry Regiment, was not formed until June 1784.[1] After the war, the Continental Army was quickly disbanded because of the American distrust of standing armies, and irregular state militias became the new nation's sole ground army, with the exception of a regiment to guard the Western Frontier and one battery of artillery guarding West Point's arsenal.
Role of the United States in the Vietnam War With the advent of Rolling Thunder, American airbases and facilities needed to be constructed and manned for the aerial effort. The defense of those bases would not be entrusted to the South Vietnamese. So, on March 8, 1965, 3,500 United States Marines came ashore at Da Nang as the first wave of U.S. combat troops into South Vietnam, adding to the 25,000 U.S. military advisers already in place. On May 5 the U.S. 173rd Airborne Brigade became the first U.S. Army ground unit committed to the conflict in South Vietnam. On August 18, Operation Starlite began as the first major U.S. ground operation, destroying an NLF stronghold in Quảng Ngãi Province. The NLF learned from their defeat and subsequently tried to avoid fighting an American-style ground war by reverting to small-unit guerrilla operations.
