Abstract
Abstract An arrangement for simulating indirect fire in military combat training exercises in which each individual exercise participant is not required to be equipped with an individual position-locating device. The arrangement uses a technique of grouping (20, 30) the players (1-7,11-17) and equipping only one member of the group with a position-locating device (43). The position of the single player equipped with the position-locating device is used to determine if the group is located within the area affected by simulated indirect fire. Once the group has been determined to be within the affected area, individual players within the group assess their own casualties based on weapon-target pairing and random chance.
