Need to deconflict with #9982

I guess array of arrays?
something like

ace_grenades_flashbangExplodeSound[] = { // Sound that is played upon detonation (file path, volume, pitch, max distance)
    {"A3\Sounds_F\arsenal\explosives\grenades\Explosion_HE_grenade_01.wss", 5, 1.2, 400},
    {"A3\Sounds_F\arsenal\explosives\grenades\Explosion_HE_grenade_02.wss", 5, 1.2, 400}, 
    {"A3\Sounds_F\arsenal\explosives\grenades\Explosion_HE_grenade_03.wss", 5, 1.2, 400},
    {"A3\Sounds_F\arsenal\explosives\grenades\Explosion_HE_grenade_04.wss", 5, 1.2, 400}
};

};

Imo we don't need to, but it would be more flexible. We could use selectRandom then instead of what is currently being done.
I'll implement the changes.
