This is the complete version of a WiC sound mod released ages ago that makes all the units of all factions to speak in their own native languages (Soviets now speak Russian, NATO has mixed voices depending on individual unit's national allegiance). All credits go to the original author who's work cannot be accessed as the file is dead from the server. The file contains sounds for all faction, lacks the installer but is installed by dropping all the files in the archive to your main WiC installation folder. Works alright with mods like Modern Warfare. Works with multiplayer, has campaign-related dialogues also. Link to the original thread upon request.
