Abstract: A communication system for sending surveillance signals in a hostile environment to an operator. The communication system comprises a plurality of relay sensors to transceive collected data between sequential relay sensors and ultimately to an operator. The communication system has a tractor for dispensing plural relay sensors throughout the hostile environment. The sensors may be dispensed by an elevator to a position where a relay sensor can be retrieved by a drone for placement to maintain line of sight communication. And relay sensors can be dispensed directly from the tractor to the ground or water. Direct dispensing of the relay sensors can occur through a hole in tractor or off a ramp.
