Can unit`s responses (from strategies, fps... actually any games that possesses such sounds) be somehow ripped from game by an amateur?
I`m thinking about Blizzard and Command&Conquer games and similar, Republic Commando, Full Spectrum Warrior (for FPS) etc.

What's unit's responses?

The response that a unit makes after you give them orders.

Yes, like "Awaiting your orders!" if ya click on 'em, or if you send them somewhere "Affirmative." or something.

Many games have them as separate soundfiles in their SFX folders, I think WarCraft III had them as .wav files.
