MetaVR Provides Visual Systems and Terrain for Stryker Training In autumn 2004, MetaVR delivered 11 multi-channel ruggedized visual systems as part of an $800K purchase for the delivery of Stryker vehicle simulators and an urban warfare terrain database. The Stryker wheeled vehicle is designed to enable the Stryker Brigade Combat Team (SBCT) to maneuver in dense urban terrain while providing protection in open terrain.
The MetaVR visual systems were coupled to a Stryker vehicle model simulation and fielded at Ft. Lewis, WA, which is the location of the SBCT. At that site Stryker combat vehicles and command and staff elements operate in a live maneuver area where the MetaVR systems are used to provide the visuals for the Stryker simulators. The 1/25th Infantry (SBCT2) trained on these simulators prior to its recent deployment to Iraq. The exercise is described in Simulations Operations Quarterly, Fall 2004, Volume 1, Issue 4 in the article, "1/25 Units Use BCST to Train at Ft. Lewis". A subset of the delivery went to the National Simulation Center (NSC) at Ft. Leavenworth, KS, where the MetaVR systems are used to create and test additional Stryker simulators.
The existing Shadow Tactical Unmanned Aerial Vehicle (TUAV) systems fielded with the Stryker Brigade Combat Team at Ft. Lewis have embedded training systems that use MetaVR visuals. These TUAV payload operator trainers, which reside in the HMMWV (High-Mobility Multipurpose Wheeled Vehicle) vehicles, are interoperable with the Stryker vehicle simulators as they all use a common visual system, terrain database, and networking protocols. The Stryker simulators are also interoperable with fielded convoy training systems at Ft. Hood, TX, Ft. Carson, CO, and Ft. Stewart, GA. Both the Stryker simulator and TUAV embedded trainer will interoperate with the DBST systems also fielded at Ft. Lewis, WA. Each MetaVR delivery included a collection of 12 Stryker entities (10 production vehicles and 2 prototypes). About the sale Ft. Lewis has 9 simulators: 2 commander versions, 7 Battle Command Skills Trainers (BCST) and 1 After Action Review for which 1 economy visual channel, 1 efficiency low-profile system were also delivered. The desktop setup of the BCST is a deployable rack-mounted system with plug-and-train capability for virtual mockup configurations such as Stryker. Along with an Infantry Carrier Vehicle (ICV) and the Mobile Gun System (MGS) these components comprise an integrated Live-Virtual-Constructive (LVC) training environment (described below). For NSC's Ft. Leavenworth LVC development and testing environment, 3 economy visual channels, 2 low-profile systems, and a VRSG and WorldPerfect license were delivered. About the database The 3.3 geocell (147 km x 224 km) database was built from 100 meter elevation data with .3 meter color covering Seattle, including Ft. Lewis and its Leschi Town MOUT site (65 km x 130 km). Microterrain was built into the MOUT site using information derived from the photographs. The database contains substantial 3D feature content modeling of the Leschi Town site, which is the Army’s largest urban combat training center. The cultural features were modeled in Blender, an open source 3D modeling application; MetaVR’s model designers made use of MetaVR’s new plugin to Blender. The buildings and other structures are photorealistic; model designers created the models from a set of approximately 200 photographs of the Leschi Town area. The building models have radiosity (soft shadows) applied to the geometry to increase their realism.
About the Stryker LVC training environment In late July 2004, units from the 1/25th Infantry (SBCT2) conducted training, during a proof-of-principle of a HomeStation LVC capability. Unit training objectives were focused on SBCT Infantry Rifle Company Battle Command in support of Security Operations and Cordon and Search. Company operations were focused in and around the Leschi Town MOUT site, with 18 Stryker ICVs and approximately 180 dismounted soldiers, opposing forces and civilians, instrumented through Cubic Defense Systems’ DSTAR Live Instrumentation System. The infantry platoons conducting operations in Leschi Town were supported by the Mobile Gun System (MGS) platoon operating in the virtual environment, through the use of the Battle Command Skills Trainer (BCST). The BCST was also used in a Stryker Command Variant (CV) mock-up for the SBCT Battalion TAC. Constructive simulations/C4I interfaces (JCATS, SELS, SIMPLE) were used to portray the remainder of the SBCT and additional opposing forces and civilians.
About the Stryker models Each MetaVR delivery included a collection of 12 new Stryker models (of 10 production vehicles and 2 prototypes) as part of the VRSG 3D content entity library; each high-resolution model has four paint schemes.
Actual and simulated views of the Ft. Lewis MOUT site Below is a series of images of the Leschi Town MOUT site. You can compare photographs of the actual Leschi Town on the left side with the VRSG screen captures of the simulated view on the right. The models of buildings and other structures are photorealistic; the models were created from a set of approximately 200 photographs of the Leschi Town area.

charge to all US Government agencies and contractors (for official use
only) and requires VRSG
