I think that you mismicroed your large mixed army. cyclopse is slower than other tank factroy units, so when you give long miove orders they can lag behind a bit whereas they should be at the front of the pack. If i were creating a mixed force of cyclopses, I would have cyclopses plus ogres, where the ogres keep behind the cyclopses andtry and deal damage where they can as the cyclopses take pot shots as foes. if the cyclopes get rushed, they'll take ogre fire. Your mixed forces had the cyclopes survive because they were at the back of the pack, too slow. you should have pulled everything else back behind them. I also don't think you lost a single cyclopes, so keeping welders near the front is still a strong point for heavy tank.
