In a NCW situation the result of a precision engagement is based on several different factors, and can therefore be difficult to predict. Simulation is in many cases an important tool to study the impact of various parameters. A precision engagement situation with network controlled artillery against enemy tanks has been simulated with ISIS to prepare for future tactical studies of NCW situations and to test the capability of ISIS as a simulation tool for this type of problems. ISIS has shown good potential for simulations on a tactical level. Some new components have been developed, but most predefined models and features of ISIS have been used for the simulation.
