What was Operation Slingshot in Vietnam?

Answer 1

I do not think it was called "Operation Slingshot"... It was called "Operation Giant Slingshot," which was a Brown Water Navy operation designed to interdict the North Vietnamese supply lines where the Ho Chi Minh trail entered South Vietnam in the 'Parrots Beak' area, where Cambodia juts into South Vietnam, west of Saigon. The operation established River Patrol and Rivron/Riverbed blocking forces on the Vam Co Dong and Vam Co Tay rivers, which bracket the Parrots Beak, and looks like a 'Giant Slingshot' on a map .The operation also involved army troops as ground forces within the riverine forces. I think it was the third Infantry, but I might be wrong on that point.
