With the COMBAT music folder track expanded, you can see that there are measures of silence between short segments of music. The silence is not intended to be heard in the final score. Breaking the music into smaller segments makes it easier to export each of these sections as a separate audio file, the asset that will later be used by Wwise. Providing Wwise with smaller building blocks provides the opportunity for Wwise to reassemble them in various orders, either randomly or based on specific circumstances of the game.
