Is "Real Hero" good? My mother once did outdoor training. After they finished, they listened to True Heroes and cried together. This song should be very atmospheric, very inspiring, and everyone knows it. Among the younger music, "Boundless Sea, Sky" and "Snail" are both good and very inspirational. I believe that using this as the background music for students' military training videos can highlight the significance of military training, which is to train them and motivate them.
