Targetry Range Automated Control and Recording (TRACR) is a common target controller used at live-fire Army target ranges. TRACR is used to control range targets (both lane based and maneuver). It provides the controller the ability to expose and conceal targets, set their properties, behaviors, etc. beyond individual targets. TRACR allows the controller to regulate the entire range, and the ability to create and play scenarios. Training typically consists of a single range tower governing the entire site. For lane based training, each lane has a trainer watching the student, but the trainer has no direct control over the events of the range and must constantly make necessary requests via radio to the controller at the tower. This creates a bottleneck at the tower and is inefficient from the trainer's perspective. Collaboratively with Army's Program Manager Training Devices and the Army Research Laboratory Simulation and Training Technology Center, the Team developed TRACR Ultra Lite (TÃœL); an Android tablet based live training app which delivers all of the target control capabilities found in TRACR into the hands of the trainer. While using TÃœL, the trainer can directly and efficiently control the trainee's exercise, allowing for a tailored training environment without overloading the tower operator. Along with lane based training, TÃœL was also designed to meet the needs of maneuver range training and serve as a tool for site maintenance. This paper will discuss the abstract concept of enhancing live training with mobile capabilities. It will discuss how mobile technologies such as smartphones and tablets can be used to enhance the quality, efficiency, and safety of live training. Specific use cases of TÃœL will be showcased and will describe how it was designed and developed to execute in unison with TRACR while meeting this criteria.
