[Mobhack]

Goto \game data\sounds and back up sounds.ini

Then play with that to identify the sounds you want to kill off, using a TEXT editor - not a word processor!.

Sounds are a simple association of a sound variable to a file name.

Start at the beginning of the list in the [soundeffects] section of the ini, then figure out what each sound file does by double-clicking on the actual sound file (WAV) in the folder.

Once you have found say the infantry "Stomping feet" march sound, editing that INI variable to equal nothing should do the trick, (Or it may need a sound file with no sound - been ages since I looked at sounds!), and so on through the list till you have identified all the "movement" noises.
