This hand-drafted briefing map documents the terrain and enemy defenses surrounding a Vietnam War-era combat search-and-rescue operation, call sign "Boxer 22." The close-up inset shows the separate survivor locations of a downed navigator and pilot along the Nam Ngo River in Laos, ringed by North Vietnamese anti-aircraft gun positions. Maps like this were essential tools for rescue coordinators and A-1 Skyraider RESCORT pilots planning how to extract downed airmen from some of the most heavily defended terrain of the war.
