The original sides were Russia, African Warlords and USA. But Russia was changed to China, since we already have Russia in Red Alert. And African Warlords were changed to GLA because of 9/11 i guess, and the need to beat up some terrorists lol.
The china infantry is called the conscript in many places of the files, like their textures
Only concept art was drawn up for russia and african warlords, a few structures, tanks and infantry. And the Russian General.
