From its first use in military operations, during a rescue mission behind enemy lines in 1944, to its crucial role in Vietnam, to the Black Hawk combat copters in the current war on terror, the helicopter changed the face of aviation-and the face of warfare. Whether they are bringing supplies and medical help or coming to the rescue of trapped soldiers, the modern battlefield could not function without them.
