Hi this is a new module for Arma 3. I've been using the triggers to give me some ambient combat sounds for missions. So I create a module so I didn't have to through up several triggers to get a good back ground noise.
Basically this is a module found in the effects category of the module section.
What it does is a loop of ambient battle sounds that's already built into arma 3. Its all random. You can set the size of the battle and intensity. Give it a try and let me know if you have suggestions.
