JVT (IMAGE) Office of Naval Research Caption A Marine uses the JTAC Virtual Trainer (JVT) during a demo at Marine Corps Base Camp Lejeune, North Carolina. JVT is one of two Office of Naval Research-sponsored systems designed to make it easier for Joint Terminal Attack Controllers (JTACs) and Fire Support Marines to train. Both systems--JVT and 3D Warfighter Augmented Reality--come in portable kits and are simple to carry. They use sophisticated, video game-style virtual- and augmented-reality software. And they're made with commercially available equipment.
