- Psionic's 3D Sound FX
A big enough collection of 'military' sound effects.
I think the format is .OGG, and there are 60 radio effects, 10 gunshots & 5 reloads. Best if ure making the next medal of honor :)
- SoundAmerica Sound FX
A VERY large (hundreds+) collection of .wavs. Come here if ure in a need of small, catchy sound effects.
