I found a couple of great sound mods on the cmmods.com site if anyone else is looking for some new sounds, they really do improve the game ten fold.
For CMBB there is the FatherOfNone sound mod which has some sounds that are in MP3 format so they will need to be converted to wave format, but thats no real problem, only took about 5 minutes for the prog i used to convert the whole lot.
And for CMAK there is the SonOfTheFather sound mod which already has the sounds in wave format.
Both have new weapons, explosions, penetration and even casualty noise's and they can be installed using the ever handy McMMM mod install programme....easy.
Big thanks to falco for pointing me in the right direction.
You can find them in the 'All/Other' section of the CMMODS database or look for the designer Oddball_E8.
Happy hunting.
