FlexTrain™ Multi-Mission Instrumentation System
Developed for the U.S. Army National Guard by SRI, FlexTrain™ is a rapidly deployable, global positioning system (GPS)-based, instrumentation system primarily used to support platoon to brigade level training. The system tracks vehicles and participants to the soldier level, allowing unit leaders to replay the day’s training scenarios and discuss lessons learned in instrumented AARs with 2D, 3D, tactical audio, and handheld video within minutes of mission completion.
FlexTrain provides the Trainer Mentor (TM) with the ability to lead the training audience through a detailed review of any moment in the recorded mission, and from any perspective. The TM can selectively display the event of interest in whatever medium best tells the story (2D, 3D, video), and the intuitive graphics allow the soldier to gain insight not otherwise possible from their position on the battlefield.
SRI has successfully deployed the FlexTrain system to more than 30 locations since 1995, including 11 exercises of 1,000 or more participants. We support the Army National Guard with platoon and company level training at seven fixed homestation sites. In conjunction with the eXportable Combat Training Capability (XCTC) program, we also operate and maintain an exportable FlexTrain system to train brigade combat teams and functional brigades at various training areas around the country, allowing Title 32 Commanders to keep their soldiers at home for more of the pre-deployment training schedule.
A 1,000-player FlexTrain system is available for rent as a standalone, participant-tracking capability, or in conjunction with other training support elements (e.g., operational support and exercise control, battlefield effects, battlefield immersion, logistics, etc.), to provide a complete training solution. The FlexTrain system is inherently flexible enough to be tailored to any military or civilian application and can also support operational and test & evaluation applications.
Key Features
During 3D AARs, units can seamlessly review specific times and training events using a highly realistic, game-like interface:
- 3D avatars show the exact locations of individual participants
- Shot lines [captured through an interface to the Army’s Multiple Integrated Laser Engagement System (MILES) training system] indicate “hits” and “near-misses”
- Synchronized video feeds provide live-action perspectives
- Tactical audio recordings allow synchronized playback of radio communications
