One of MVRsimulation's several urban warfare terrain databases is the geospecific high-resolution virtual Leschi Town training facility. This virtual site was modeled after the actual Leschi Town combined arms collective training facility (CACTF), located at Joint Base Lewis-McChord (JBLM), WA.
This virtual Leschi Town is used by the 5th Air Support Operations Squadron stationed at JBLM in their JTC TRS dome simulator and JTAC-TACP/Operational Simulation Suite (J-T/OSS) v2.0 Desktop simulation suite, for which Virtual Reality Scene Generator (VRSG) provides the visuals. JTAC trainees routinely conduct training events at the actual Leschi Town.
This virtual site is used for pre-mission rehearsals and simulated CAS missions for both JTACs and JFOs. For trainees who complete pre-mission rehearsals in the simulator then go on to train at the actual MOUT site, the simulated urban site improves their situational awareness and enables them to get to know the area before they set foot on Leschi Town.
About the Leschi Town facility
Joint Base Lewis-McChord is a United States military facility located south-southwest of Tacoma, Washington. The facility is part an amalgamation of the United States Air Force's McChord Air Force Base which merged in February 2010 into Joint Base Lewis-McChord.
Laid out like a generic urban center, the Leschi Town CACTF is designed to train soldiers how to maneuver the complexity of urban streets and multi-level structures.
About the virtual Leschi Town
MVRsimulation’s .25 sq km virtual Leschi Town MOUT site was built from 0.30 meter per-pixel (mpp) resolution USGS imagery blended with 1 mpp NAIP imagery surrounding the area. Elevation source is USGS 1 meter LIDAR blended with USGS NED 1/3 (10 meter). The terrain was built in the latest version of MVRsimulation Terrain Tools for Esri ArcGIS in VRSG round-earth terrain format.
The virtual MOUT site contains substantial 3D feature content of the Leschi Town site. The 52 geospecific MOUT building models have interiors, multiple levels, and articulated windows and doors.
The terrain also makes extensive use of over 100 other cultural elements, such as bridges, signs, sewer pipes, power transformers, street lights, curbs, barriers, tombstones, metal gates, swing sets, carports, various kinds of fences and barriers, ventilation shafts, drain spouts, picnic tables, flag poles, debris piles, manhole covers, electric utility panels, and a culvert. Over 27,500 tree and vegetation models round out the scene.
The models were created in Autodesk 3ds Max or Maya modeling tools from hundreds of photographs of the Leschi Town area, most of which are available from public sources; 200 photos were made available to MVRsimulation shortly after Leschi Town facility was built. The models were then geolocated on their terrain footprints with Scenario Editor.
Actual and simulated views of the Leschi Town training site
Below is a series of images of the Leschi Town training site. You can compare photographs of the actual Leschi Town on the left side with the VRSG screen captures of the simulated scene on the right.
Reference photos of the actual Leschi Town were captured from public video footage of the Washington National Guard 205th Training Regiment conducting Officer Candidate School (OCS) Phase III training.

VRSG's simulated view of the same scene
MVRsimulation's virtual Leschi Town MOUT site is available as part of the Northwest US region of CONUS++ 3D terrain, and available to all customers who are on active VRSG software maintenance and are US Government agencies or contractors (for official use only). For US-domestic use only. The terrain is provided in MVRsimulation's round-earth terrain format and will only run with the latest version of VRSG.
