Small military units conducting hostage rescue, scouting and training missions depend on radio communications to coordinate actions with each other and their commanders. In some areas, such as in caves or jungles with heavy foliage, mobile radio frequency (RF) communications are difficult to sustain. In World War II, for example, radio communications in tropical jungles required the use of long strings of wire as a transmission medium.
Recent developments in RF mobility gain – the technique of moving radios to locations where they can better access power for transmission have made it possible to construct a dense, 3D mesh network of radio relays that can support and augment communications for reconnaissance and hostage rescue missions, for example.
