The objective of this research was to evaluate the effect of advanced interface features on an operator's ability to perform the duties and responsibilities associated with the role of Platoon Leader (PL); maintain and monitor vehicles in a formation, respond to communications, and maintain security around his vehicle. Participants conducted a military convoy mission using a basic interface (representative of the current force technology) and an interface with advanced warnings, cautions, and alerts (WCAs). Participants completed two missions with each interface configuration. Results showed that the advanced interface significantly improved the PL's ability to respond correctly and quickly to vehicles deviating from the formation. Further, participants reported better situation awareness and lower workload with the advanced interface than the baseline interface. Appropriately applied advanced formation tools such as vehicle status information and WCAs do improve military effectiveness and are important for military operations.
