“Mindfulness-based Mind Fitness Training”（ MMFT, pronounced M-Fit） is a new mental training approach for enhancing performance and building stress resilience of US troops, and to make stress inoculation training existing in troops for a long time more effective. This article explores how MMFT is carried out systematically in US army from its content of courses, the ways to practice and contemporary research on MMFT. The conclusion indicates it is necessary to introduce mindfulness training into ROC Armed Forces. There are three reasons. First of all, empirical research has proved that mindfulness training obviously benefits soldiers’ body and mental health. Furthermore, it also enhances their emotional regulation and cognitive performance. Secondly, mindfulness training is a low cost and uncomplicated training, and once you learn it, you will benefit from it for life. In other words, it will not increase troop’s burden of existing training; on the contrary, it can create greater efficiency. And lastly, MMFT could make stress inoculation training more effective. Depending on the development experience of MMFT, the author suggests that ROC Armed Forces could integrate mindfulness training into military and mental training during different periods of military service. Besides, the author would invite people with lofty ideals to get involved in the study of mindfulness training for active-duty troops and promote professional development of military psychology in Taiwan.
