This reference map of the Laos-Cambodia-South Vietnam border region documents the geography central to Operation Tailwind, a covert MACV-SOG ground incursion into Laos in September 1970 aimed at disrupting North Vietnamese Army supply and logistics operations along the Ho Chi Minh Trail. Maps like this were essential tools for planning and understanding cross-border special operations conducted with close air support from U.S. Air Force aircraft, including A-1 Skyraiders.
