(GDT) was founded in 2017 by Lisa and Tom Prentice to serve the Military and Public Safety Communities. Having had long careers in Corporate America, in advanced information technology and operations management, it was time to forge a new path. One that provided the gratification of serving those who serve us.to be well aligned with a ranchfacility outside of Austin, Texas, called Reveille Peak Ranch, or as we call it, the "Ranch". For the last 15 years, this 1350-acre ranch has provided military and public safety personnel a remote and austere training environment at little to no cost.​hat between our backgrounds and the Ranch's resources, both natural and man-made, we had the perfect opportunity to provide technology focused solutions to our clients. We formalized our relationship with the Ranch, and it became our base of operation.a small fire accidentally started during a field training exercise. Luckily, we already had a group of local firefighters, with a drone, on scene. It was by happenstance that we were introduced to tactical robotics, specifically unmanned aerial systems (UAS) and the roles they played in taking on challenges faced by the members of the fire service. It became apparent there were several areas of need: the ability to test and compare drone platforms, in-the-field practical training environments, communications technologies, power systems, and analytics software.
