"All evolutians in the military" might make sense to the military mind of Yao Yuan but I almost choked when I thought of Ivan and Bo Li sent to get shot at by robots.
There are so many needs that a non-military evolutian could help out in, especially since technology is a big concern. So maybe Xiao Niao isn't a scientist, but a Thinker should be an ace engineer or technician or even administrator. It's obvious at this point that tech development is more influential to their survival than more soldiers.
