Abstract:  
Introduction: Military missions involve stressful and life-threatening situations; however, soldiers should have a healthy cognition in the battlefield despite their high level of stress, which is an ability that should be gained during prior military training. A successful and influential training is suggested to be associated with structural and functional improvements of the brain.
Methods: Therefore, in this study, the pattern of brain activation while observing videos relevant to life-threatening situations, in addition to brain structure, were compared between 20 military members and 26 normal controls, both male, between 19 to 24 years old, right-handed, studying in the BSc level, and from the same socioeconomic status.
Results: The results showed larger volume in a total number of 1103 voxels of the brain (in 5 brain areas) in the military group. Furthermore, the military group had higher brain activation in the visual processing areas of the brain when observing real combat videos, whereas this increment was mostly in the areas associated with motor processing and executive functions in controls.
Conclusion: This study showed that military training is associated with positive structural changes of the brain, and with a different brain activation in response to stressful situations, both showing the importance of a qualified military training.
