Annotated Topographic Map of Chevane Airfield Area, Laos, with 20-Kilometer Radius Markers – Operation Tailwind Reference Map, Joe Parnar Collection
This annotated topographic map centers on the Chevane airfield in southeastern Laos, a key reference point during MACV-SOG's Operation Tailwind in September 1970. Hand-drawn arrows marking 20-kilometer distances illustrate the operational planning considerations—such as strike aircraft range and extraction distances—associated with this deep cross-border reconnaissance mission into hostile territory along the Ho Chi Minh Trail.
