Since this was a networked simulation, each simulation station needed its own display of the shared virtual environment. The display stations themselves were mock-ups of certain tank and aircraft control simulators, and they were configured to simulate conditions within the actual combat vehicle. The tank simulators, for example, could accommodate a full four-person crew complement to enhance the effectiveness of the training. The network was designed to support up to several hundred users at once. The fidelity of the simulation was such that it could be used to train for mission scenarios and tactical rehearsals for operations performed during the U.S. actions in Desert Storm in 1992 (Robinett 1994).
