I play a lot of pubg(player unknowns battlegrounds) and you can often hear the bullet whizzing past you before the initial shot of the gun/rifle/bullet. And you can often gauge how far away someone shot because of this.
Which is why more elaborately funded real-World armies are deploying suppressors on line-issue rifles.
Without the muzzle report the enemy has a much more difficult task in assessing distance and direction to the source of fire.
combat flight simulators like DCS and IL2 have this.
