As the US Army has been at war for over a decade, the art of developing and conducting Home Station Training (HST) has not been a focal point for our next generation of leaders. Units have become accustomed to having their training provided to them by others prior to overseas deployment. This diminished capability has made it difficult to develop and execute effective HST when that training includes live, virtual and constructive (LVC) environmental considerations. To fully understand the scope of the problem, this paper articulates the processes in which HST is currently designed and developed, and how that training could be supported by Mission Training Centers (MTCs). The process, while not the same for all units, demonstrates the genesis of how training is developed at home station. To help overcome the challenges, the Training Brain Repository-Exercise Design Tool (TBR-EDT), a collaborative, web-based repository and exercise design tool has been created. It enables commanders and staffs to reuse storylines, events, and other exercise related items from within the repository. It allows units to work closely with MTCs to automate and modernize HST lifecycles. The TBR-EDT revolutionizes the current mainstream exercise design process; reducing the time required to develop an exercise and its associated training support package (TSP), due to the enhanced collaborative opportunities between the training unit and the supporting MTC. The TBR-EDT currently supports simulations with start of the exercise (STARTEX) data, provided in multiple machine readable order of battle service, extensible markup language (OBS XML) versions for import into simulation systems. In the future, more robust STARTEX conditions such as terrain, C2, and parametric data will further enhance the simulations environment, and better replicate the operational environment. Finally, the paper will present the TBR-EDT as a game changer for Army and Joint trainers; significantly shortening the design process for realistic and economical HST exercises.
