Basically a number of WAV files taken from CNC: Generals and were left in RA2 audio format (PCM 22050 hz, 16 bit, mono.) These are not sounds which were used for units but instead used in opening or closing cutscenes for the American faction.
However, they can be used for custom airstrikes or even serve as a voice for a unit.

IMPORTANT: If you use these sound files, you must credit EA and CNC:Generals.
