Here is a good article discussing how the USMC is leveraging DVTE's:

From Wikipedia, the free encyclopedia

The Deployable Virtual Training Environment (DVTE) is a laptop based platform for a wide variety of training simulations in the USMC.TRASYS web. DVTE consists of two main components, the Combined Arms Network (CAN) and the Infantry Tool Kit (ITK). The current version of the CAN was developed by the ONR VIRTE program as part of its Demo 3 and is based on the JSAF simulation. It uses the Open Source Delta3d toolkit for visualization. Each laptop can be reconfigured to simulate a variety of USMC platforms including the M1 Abrams, Amphibious Assault Vehicle (AAV), LAV-25, AV-8 Harrier II, and the AH-1 Cobra. A typical DVTE suite consists of 32 laptops and a modified NVisor SX Head-mounted display (HMD).
The Infantry Tool Kit consists of a number of stand-alone games and simulations. The main simulation is a first-person shooter called VBS. Other applications include: the DARPA developed DARWARS Tactical Iraqi (part of the Tactical Language & Culture Training System family) and the ONR developed Close Combat: Marines, MAGTF XXI, and TacOps MC.
