I have always thought Arma had odd sounds.. being in the military 7 years and been deployed, I lose my immersion when I hear the sounds in arma.. I know A2 just used generic sounds but Arma3 shouldn't be. It takes me out of my immersion. I started playing SQUAD.... They have hit the nail on the head! For instance, an RPG rocket shouldn't sound like a cannon lmao it literally sounds like a big bottle rocket! The dev at SQUAD doing the sounds is really knowledgeable on firearms.. he is getting real recordings of the weapons in game. It is completely insane how realistic it is. Gives you chills. I LOVE Arma.... but the sound department is pretty weak. Other than that, the game is great. I literally have been playing squad just because of the sounds they use for their weapons. lol
