The constant threat to all American aircraft missions was the Russian built missile known as SAM, which employed various levels of sophistication. One counter action taken was the Wild Weasel mission: Weasel pilots would fly ahead of other aircraft, exposing themselves to enemy radar lock-on, so the Shrike missile they carried could use the same signal to target enemy ground-base, and thereby clear the way. The fascinating legend of Wild Weasel has never been told before today.
