Thank you!
Yes, the universe is fictitious so all the units will be non-historical. The current vehicle models are placeholders. The units will be based loosely on the early cold war. I'd like to have a research tree that lets you unlock helicopters, atgms, better planes, etc. However these are still a long way off.
The anime aspect won't affect the wargame-style gameplay too much. It's more about the aesthetics, the story, the characters.
