There comes a time in war when man is pitted against man, a time for the individual without his weapons. Such a time, the Navy knows, may come to its pilots--possible in the rankness of enemy-infested jungle, on the beaches, or in the desert. In preparation for that eventuality, aviation cadets are taught the finer points of hand-to-hand combat. So that it may be instinctive, the Navy teaches cadets to fight blindfolded, such as they might have to do in the jungle at night.
