This 1971 page from a U.S. Air Force F-4 Phantom operations manual details procedures for onboard sensor and defensive systems: the KB-18 strike camera used to record bombing results, the Type IV camera pod for reconnaissance and gun-camera footage, and the ALQ-71 and ALQ-87 electronic countermeasures (ECM) pods used to jam enemy radar and protect aircrews from surface-to-air missile threats over Vietnam. A handwritten pen annotation in the margin reflects an in-field correction or update made by an aircrew member or instructor. Project: 218451
