Electronic Intelligence, Countermeasures, Elint, Electronic Warfare: The logo symbol is a Raven. During the Vietnam Conflict, 1968-69, at Takhli Royal Thai Air Force Base, Thailand, our ECM troops adopted 3 newly hatched Ravens. A black bird is an extremely negative omen to the Siamese, so some children destroyed a nest, leaving the newly hatched young birds to die. We raised these three hatchlings on hamburger, 'predigested' with Coca Cola. More in the captions.
