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.

(The answer to the question is: They are placements for Tiberium Wars style 'upgrade objects', which are not visible in this image)

Remind me, was Industrial Plant meant to be the tier up building for Soviets? Because as-is this one and new Soviet building are almost identical in shape, so giving them different functions would make them very confusing.
Also, upgrade unlock props are a nice tidbit, nice to see you're recreating that.
"Very confusing" is a stretch, however there could be some confusion. I might consider swapping the roles between the Soviet Alpha Lab and the Soviet Tech Center.
