1. A military wireless communication terminal for a soldier, comprising:

  • a global positioning system receiver for receiving global positioning system signals and outputting location information of the terminal based on the received global positioning system signals;

    a terrestrial magnetism sensor for sensing azimuth of the terminal;

    a memory in which map information of an operating area is stored;

    a location transmitting unit for periodically transmitting terminal location information output from the global positioning system receiver;

    a radio communication unit for transmitting and receiving signals from a designated originating place;

    a military force location information processing unit for generating military force location information from a signal received from the radio communication unit;

    an absolute azimuth calculator for correcting sensed azimuth by the terrestrial magnetism sensor based on the terminal location information and outputting azimuth information;

    a map information reading unit for reading map information based on the terminal location information;

    a location information overlaying unit for overlaying the azimuth information, the military force location information on the read map information;
