Ten Technologies: A Brief Look at Military Evolution – Modeling and Simulation

By Carla Voorhees,

This is the final in a series of 10 technologies integral to the United States military since World War I.

All branches of the military rely on modeling and simulation for planning purposes, war games, training, exercises, development of new technology, and many other reasons.

There is a tactical advantage to war-game modeling: using maps, figurines, virtual reality and full-scale exercises allow warfighters to “see” a battle beforehand and prepare for the challenges they will face. Virtual sand tables are making that even easier, showing terrain and building representations in an easy-to-use format.

Modeling and simulation can also be used to develop new technology. How a new technology will perform can be tested both virtually and in the lab. For example, a new aircraft wing shape can be drawn on a computer and then tested in a wind tunnel. Both sets of tests are a form of modeling.

Additionally, new technologies can be tested and evaluated for human compatibility. Ultimately, the end user must be able to understand the system and be able to interact with it in a comfortable manner, both physically and intellectually. Labs such as the Usability Lab run by the National Center for Telehealth and Technology are great examples of this type of simulation.
