A Dangerous Business: Forward Air Control in Southeast Asia
DAYTON, Ohio - FACs flying night missions often used Starlight scopes to find the enemy hiding under the cover of darkness, but the USAF continued looking for better night vision systems. In 1971, the USAF equipped the OV-10 Broncos flown by the 23rd TASS with the AN/AVQ-13 PAVE NAIL, a stabilized periscopic night sight and laser designator. Not surprisingly, the 23rd TASS took the call sign of Nail. This patch shows an OV-10 over a red nail, and the black patch indicates the darkness of night. (U.S. Air Force photo)
