The MAGTF Tactical Warfare Simulation (MTWS) is the Marine Corps only constructive, aggregate resolution simulation system used to support the training of Marine commanders and their battle staffs in MAGTF warfighting principles/concepts and as well as associated command and control procedures. Using complex computer-simulated behavior models, MTWS provides an interactive, decision-based, real time, war game representing the six warfighting functional areas of command and control, maneuver, fires, intelligence, command and control, logistics and force protection. Its modeling breadth and flexibility enables users to represent and exercise a wide variety of combat scenarios to prepare leaders to face the military challenges of today’s world. MTWS is designed to support the training of commanders and their staffs in exercises involving live and simulated land, air and Naval forces at all operational command levels. The system supports all levels of command throughout the Marine Expeditionary Force (MEF) and Joint Task Force (JTF). MTWS can be used as a multi-sided wargame, including red, blue, civilian, and non-aligned sides. The system can also be used to validate specific operational plans against a variety of enemy and environmental situations.
