A UH-1 "Huey" helicopter banks low over dense jungle terrain, with a smoke marker rising from the canopy below to guide the crew to a landing zone. Helicopters like this one were the lifeline of MACV-SOG reconnaissance teams operating deep inside Laos and Cambodia, inserting and extracting small units under intense time pressure and often under fire. This image is associated with Operation Tailwind, a September 1970 MACV-SOG incursion into Laos. Project: 219518
