Model.  Models come in many forms.  Models can be relatively simple.  A model of the solar system showing the relation of planets and their orbits around the sun is a model.  In the combat development process computer models are used to replicate physical processes without the expense of operating equipment or deploying personnel.  In selecting the models to be used, the team may choose a combination of models to get a more realistic picture of system performance and characteristics.  Additionally, models are now being used effectively in conjunction with live systems.  In such applications, a model may be used to stimulate a radar screen indicating the presence of an enemy target.  The model(s) selected must be sufficient to support the data and scenario requirements of the project.

In an operational test, the model may consist of process diagrams showing decision trees, or information acquisition, collection, processing and flow procedures necessary to attack a target.  In short, the model provides an easily understood view of what is expected to happen.

FireSim XXI.  In 1996 Tec-Masters began to develop a modeling and simulation capability that was based on the need to support the Field Artillery’s modernization effort as it related to the Systems Engineering and Technical Assistance (SETA) contract that had been awarded in 1992.  Since that time the Army has awarded two subsequent SETA contracts (1997 and 2003) to Tec-Masters.  A large number of the SETA Task Orders require experience and expertise in with models in use by the Army’s analytical community.  The majority of the modeling and simulation related support provided by Tec-Masters involved the operation, maintenance and expansion of FireSim XXI, the Army’s primary model for indirect fires.  In addition, Tec-Masters provides critical support to customize FireSim XXI input/output to ensure that it can be used as part of a confederation with other models to accurately reflect the battlefield environment.

Tec-Masters also uses other models to support analytical tasks associated with the SETA and other contracts.

Simulation.  Tec-Masters operates and maintains FireSim XXI which is an integrated Distributed Interactive Simulation (DIS) environment for fires that incorporates tactical command, control, communications, and computer, and intelligence devices.  FireSim XXI provides an environment that readily supports research Developments and Analysis efforts, Advanced Concepts Requirements and unit collective training.  Recently, Tec-masters has teamed with the University of Texas to integrate the Extensible C4I Instrumentation Suite (ExCIS) model with FireSim XXI the resulting configuration (called FX XXI) permits direct digital communications between the simulation and the Advanced Field Artillery Tactical Data System (AFATDS). 

Using FireSim XXI, Tec-Masters has:
