Just as the parachute introduced a third dimension to the battlefield and created AIRBORNE units during WWII...the helicopter added to the already existing 3rd dimensional battlefield but created the AIRMOBILE divisions in Vietnam. Airmobile infantrymen were capable of fighting two or more battles in one day! Whereas WWII infantrymen normally fought one battle in one day (since they had to walk there while Vietnam grunts flew).
Approximately 12,000 US helicopters were deployed in Vietnam.

During his presidency, John F. Kennedy escalated U.S. involvement in Vietnam through several key actions. He increased the number of military advisors in South Vietnam from a few hundred to over 16,000 to assist the South Vietnamese government in combating the communist Viet Cong. Kennedy also authorized the use of U.S. helicopters and other military equipment to support South Vietnamese forces. Additionally, he approved the strategic use of covert operations to undermine the communist influence in the region.

The US employed ALL OF IT'S CONVENTIONAL military assets in conventional and unconventional warfare in the Vietnam War. "Atomic" weapons and "Chemical/Biological" weapons were the only assets not used.
You're referring to a helicopter gunship. Made popular in Vietnam, the French actually employed them first, mounting weapons onto H-21 and H-19 helicopters to provide close air support. This was done as the lighter helicopters of the time did not have enough power to sufficiently mount and carry weapons. These came about before dedicated attack helicopters made their appearance, and were replaced in the gunship role by those dedicated attack helicopters.
