As new technologies are developed and "spun out" to the U.S. Army, effective training of its Soldiers, leaders, and units to employ these technologies will be essential. To support the timely development of new technology training, initial Tactics, Techniques, and Procedures (TTP) will need to be developed before the capabilities are actually produced. Because of this, traditional methods for developing TTP may not be adequate. Thus, there is a need to investigate TTP development methods to augment traditional methods. These new TTP development methods must provide structured activities to measure, assess, and guide the TTP development process, but must also be flexible enough to respond rapidly to a wide range of conceptual constructions. The goal of the research described in this paper was to create a future-focused method for developing TTP. The approach harnessed knowledge elicitation methodology and simulation-based vignettes to provide a flexible set of tools to structure and guide the TTP development process. As a proof of concept, the methodology was used to develop TTPs focused on the combined employment of the Future Combat System Class I Unmanned Aircraft System (UAS) with existing (and Spin Out 1) capabilities. The resulting developer's support package was implemented with Soldiers to obtain feedback and ideas for improving the method. Facilitating TTP development via the structured knowledge elicitation (KE) process was productive across four wide-ranging simulation vignettes. The effectiveness of the method was measured by participant ratings as well as the research team's ability to implement the process. A majority of participants and researchers rated all aspects of the KE method highly, with the only exception being the technical aspects of the simulation. The method produced high-quality TTP that could provide a firm foundation for developing future training. Lessons learned and future recommendations are provided.
