Pretraining and posttraining tests were carried out in 2 forms to evaluate the training effectiveness: one was knowledge acquisition regarding the NTS and the other was a real-world, scenario-based test. In addition, the students were asked to rate their agreement with a series of survey items on a 5-point Likert scale. Results: A battlefield geographic environment, tactical scenarios, scenario-based decision software, large-space teamwork, and virtual interaction system modules were successfully developed and combined to establish the mixed-reality training platform for BFA. The posttraining score of the students’ knowledge acquisition was significantly higher than that of pretraining (t=−12.114; P≤.001). Furthermore, the NTS score and the total score that the students obtained in the real-world test were significantly higher than those before training (t=−17.756 and t=−21.354, respectively; P≤.001). However, there was no significant difference between the scores of technical skills that the students obtained before and after training. A posttraining survey revealed that the students found the platform helpful in improving NTSs for BFA, and they were confident in applying BFA skills after training. However, most trainees thought that the platform was not helpful for improving the technical skills of BFA, and 45% (9/20) of the trainees were not satisfied with the simulation effect. Conclusions: A scenario-based, mixed-reality platform was constructed in this study. In this platform, interaction of the movement of multiple players in a large space and the interaction of decision-making by the trainees between the real world and the virtual world were accomplished. The platform could improve the NTSs of BFA. Future works, including improvement of the simulation effects and development of a training platform that could effectively improve both the technical skills and NTSs of BFA, will be carried out. %M 36472903 %R 10.2196/40727 %U https://games.www.mybigtv.com/2022/4/e40727 %U https://doi.org/10.2196/40727 %U http://www.ncbi.nlm.nih.gov/pubmed/36472903
