But a two-weeklong exercise in the Utah desert gave those aboard three UH-60L helos unprecedented intelligence as they raced to their objective. The crew at exercise Edge 21 received Integrated Visual Augmentation System, or IVAS, goggles as well as tablets that allowed them to see through aircraft and provided to-the-minute mission updates based on real-time intelligence collected from air-launched effects sensors.
