Bohemia Interactive Simulations (BISim) is a global software company at the forefront of simulation training solutions for military and civilian organizations. BISim develops high-fidelity, cost-effective technologies for tactical military training and simulation. We apply game-based technology to a range of breakthrough, military-specific training and simulation software products.


Our History

Since the company's start in 2001, BISim has produced state-of-the-art serious game products. Evolving from the gaming industry, the company focused on the development of the Virtual Battlespace series, which delivers flexible, high-fidelity, virtual environments. Virtual Battlespace (VBS) allows multiple participants to train simultaneously for a wide range of tactical activities.

In January 2009, Virtual Battlespace 2 was named the flagship of the Army’s “Games for Training” program. In July 2013, the U.S. Army again selected BISim and partner companies to deliver Virtual Battlespace 3 (VBS3) to its “Games for Training” program.

Today, many western militaries use VBS for daily tactical training and mission rehearsal. BISim has important, enduring contracts to support military organizations including the United States Marine Corps, United States Army, United Kingdom Ministry of Defence, Swedish Armed Forces, Canadian Forces and Australian Defence Force.



With operations in the United States, the United Kingdom, Australia, Poland and the Czech Republic, BISim is positioned to help customers where they need us. In addition to our corporate locations, BISim maintains strong relationships with partners and resellers all over the world. 


Training and Simulation development services

To help customers engage the full potential of BISim’s products, we offer training and development services for all of our current products. With clients in dozens of countries, BISim maintains a global focus.

We have training facilities and development studios in Australia, Czech Republic, Poland, United States, and the United Kingdom. Our development efforts concentrate on delivering state-of-the-art technology to meet the specific needs of military customers and directly support troops on the ground. BISim provides professional training support to customers in all domains of VBS use, including content creation, terrain generation, scripting, and exercise administration. BISim offers three types of courses: standard courses at our training facilities, custom on-site courses and online courses.


Riverside Investment

In January 2013, the private equity firm, The Riverside Company, acquired BISim. This acquisition enables BISim to further expand its multi-national operations and development teams, and it supports ongoing development of VBS.


TerraSim acquisition

In April 2013, BISim acquired TerraSim Inc., the developer of TerraTools® and several source data preparation products used to simplify simulation database development. TerraSim is the technology leader in commercial products enabling the rapid production of correlated terrain for visual, constructive, and serious game simulation systems.

This merger supports BISim’s commitment to extending the capability of VBS for tactical training and mission rehearsal, and supporting ever-larger terrain content requirements.
