Slingshot

It is Christmas in Vietnam, 1968. Terrible heat and wilting humidity mark just another day.

At a desolate base camp in the northwest corner of the Mekong Delta, near the Cambodian border, a helicopter touches down and a stout little Hispanic man dressed coolly in khaki trousers and white shirt steps onto the ground. The military and political credentials of Mr.Mendez will prove to be unclear, which means he is CIA.
Big shots rarely visit the camp at Tra Cu. It is home base for operations of all sorts, from conventional to far from it. From Tra Cus barbed wire perimeter one can mount just about any kind of overt or covert mission. Mix or match an Army Special Forces A Team, a Navy SEAL detachment, South Vietnamese Army Rangers, mercenaries from Cambodia and even Laos, and patrol boats and crews of the Navys River Patrol Force.

Mr. Mendez needs a boata patrol boat and crew to run him up a narrow river, deep into territory held by the North Vietnamese and Viet Cong. Their objective will be to buy the freedom of a downed American pilot, held by a gang of Viet Cong guerillas. In a setting amazingly similar to that of the renowned film Apocalypse Now, this mission begins.
