r Army operations in mid-intensity combat. Current software is bound to proprietary operating systems and hardware. The software design, especially the underlying representation of terrain, precludes representing the detailed functionality required for resolving the high resolution interactions needed to train commanders and battle staffs at levels from battalion to operational levelcommanders in joint scenarios for war and operations other than war.4. Capabilities Required. WARSIM 2000 will support commander and battle staff training from battalion up to theater level. While the major simulation models of WARSIM 2000 will run on computers housed in fixed regional facilities, transportable Simulation Support Modules (SSMs) will provide support functions under the control of a senior controller at locations near the training unit. Users of the simulation will train under the guidance of a senior trainer, usually the unit's commander, the next higher level commander, or an instructor at institutions. WARSIM will provide users a complete training environment consisting of simulations, data, support functions and communications. a. System Performance. The following description of requirements for the WARSIM 2000 training environment addresses in turn each of the functional components described in paragraph 1.b. (1) The Simulation. WARSIM 2000's simulation component must have the following functional characteristics. (a) General Attributes. (i) Size. The model must be large enough to support a multi- echelon corps or theater exercise. The model must also be able to link to other copies of itself to support larger exercises. The simulation must also be able to support multiple, concurrent, smaller training exercises, such as several battalion headquarters training independently. (ii) Weather. The simulation must accurately portray the impact that weather elements have on operations (spac...
