1962 in the Vietnam War

January
Operation Chopper occurred on January 12, 1962 and was the first time US forces participated in major combat in the Vietnam War. This operation heralded a new era of air mobility for the U.S. Army, which had been slowly growing as a concept since the Army formed twelve helicopter battalions in 1952 as a result of the Korean War. These new battalions eventually formed a sort of modern day cavalry for the Army.
