Command & Conquer Red Alert History is a small mod that adds a few new units. The idea came about because I wondered what a few Red Alert units would look like and perform inside the Tiberium wars engine. I consider this mod a 'museum', wherein I add a few historical pieces that I like into the C&C3; engine! The Mod will be updated by adding a few units at a time (typically around 10 items). The mod is a mixture of mostly EA & public models, as well as a few original models done by me. Check the forums & articles for detailed information and for in-depth discussion.
