Probably a 2 part question, but where are the unit wavs located? I've found the ones used in missions (there's a ton of unit tutorials for each side) found those in speech english. There's a bunch of sound effects in audio. Also, is it easy to add your own music/sound effects in?
All the unit sounds are in audioenglish.big they're named systematicly. i for infantry, v for vehicle etc. and then the abreviated unit name (pat for pathfinder etc.) and then when the sound should be used.(di for dying se for select etc.) To know quickly what sounds are used open voice.ini.
