This little file changes the sound of your MP5 to sound as if it were silenced. It can also be used as an alternative silenced weapon sound for your silenced pistol.
Install this MP5 sound into Objects_client.zip located in:
C:\Program Files\EA GAMES\Battlefield 2\mods\bf2
P.S. This can also be used for the Silencer pistol
Oh and use how every you like ;-)
