The Digital Battle Command Team Training (DBCTT) courseware is designed to improve the coordination skills of Army battle staff teams involved in dynamic mission planning and execution within the digital Tactical Operations Center (TOC). The DBCTT Training Support Package (TSP) includes didactic training, a series of progressively more complex interactive practical team exercises, performance feedback, and a Performance Evaluation System (PES) to measure team coordination performance. The DBCTT TSP incorporates essential Army Battle Command Systems (ABCS) functionality through emulations to provide practical exercises in teamwork and is designed for use on currently available computer systems. The DBCTT Train-the-Trainer TSP provides training for DBCTT instructor/facilitators. This paper describes the DBCTT TSP course design and key findings from the summative evaluation. The evaluation of the DBCTT TSP showed that teamwork performance ratings for the trained group exceeded those of an untrained control group by 29%. In addition, the evaluation revealed that situation awareness was improved by 30% in the teamwork trained group. The DBCTT and Train-the-Trainer TSPs are available for use by institutional and unit trainers of battle staff in echelons brigade and below digital TOCs.
