Today's military is changing. We are changing the size and structure of our forces, reevaluating our missions, and looking at military applications of new and emerging technologies. Simulation will play a key role in aiding decision-makers during these changes. This thesis demonstrates the development and use of simple, single-purpose simulation models. These models answer specific questions and can be created quickly with readily available tools. The simulation developed in this thesis is designed to serve as a basis for further studies involving the Longbow Apache. This simulation is a stochastic, process- oriented, event-step model. To demonstrate the use of this model, a comparative analysis was performed to evaluate two field artillery "call-for-fire" procedures. Is a proposed call-for-fire procedure based on new digital technologies superior to the current process? The experiment incorporated a pre/ post-process design resulting in paired observations of the artillery's effectiveness before and after incorporation of the new technology. Results indicate the proposed procedure is superior to the current procedure. Sensitivity analysis was also performed on two input parameters as a three-by- three factorial experiment. This analysis concluded the previous results were sensitive to the specific parameter values chosen. Recommendations are made for model improvement and topics for future study.
