Muscatatuck Urban Training Center - As Real as it Gets

Muscatatuck Urban Training Center (MUTC) offers users a globally unique, urban and rural, multi-domain operating environment that is recognized as the Department of Defense’s (DOD’s) largest urban training facility serving those who work to defend the homeland and win the peace.

Muscatatuck is a real city that includes a built physical infrastructure, a well-integrated cyber-physical environment, an electromagnetic effects system and human elements. Muscatatuck offers realistic, flexible and affordable training and testing scenarios. The site supports customized live/virtual/constructive (LVC) training, developmental testing and evaluation.

The multi-domain environment includes a physical metropolitan infrastructure, a 1,000 acre urban and rural landscape with more than 190 brick-and-mortar structures with roughly 1.5 million square feet under roof, 1.8 miles of subterranean tunnels, a cave complex, more than nine miles of roads, managed airspace, a 185-acre reservoir, and a cyber live-fire range. The cyber range, or CyberTropolis, is capable of supporting live offensive and defensive operations for all three tenants of multi-domain operations (MDO) at any echelon through live/virtual/constructive (LVC) training platforms. This integrated MDO environment touches the 21st Century battlefield domains of land, air, maritime, cyberspace and space and includes the electromagnetic spectrum and information environment. As users regularly add role-players to create dense urban terrain (DUT), the unpredictable realism slows operations while increasing the speed and complexity of tactical engagements.

Everything in the city and surrounding property, including the people, is “in play.” Culturally authentic animals and role players can participate in exercise scenarios that are customized to user needs by subject matter experts (SMEs), who design foreign and domestic scenarios to replicate the most complex and dynamic multi-domain environments in which U.S. forces, DOD civilians and first responders operate. MUTC offers a robust and realistic electromagnetic environment, telecommunications infrastructure and a well-developed, closed network wireless environment.

MUTC employs a “network effect” operating model to generate two major values for the user: A highly realistic training/assessment environment at a cost-benefit ratio virtually impossible to achieve if attempted alone; and, the opportunity to collaborate as a “team of equals” with other agencies and entities that will be critical to mission success. Collaboration is effected while ensuring that each agency retains total control of its program.

 

 

The Indiana Defense Network (IDN), bestindefense.com, works with private contractors to arrange training and use of Atterbury-Muscatatuck. Foreign operators must abide by international trade regulations and follow procedures outlined by the U.S. Department of State.
