Ostwinds in WW2 were really rare (even the game says it). Why not make them doctrinal?
*WARING Im about to go wild.
Make it docrinal. Put it in T2, same cost, Or T3 with a cost reduction (make it 60F). Buff its AA. Buff a little its suppression (not its damage). New ability: Gets static, cant target grownd, double range (to shoot planes)
Ppshs were super common, but every single unit with them is doctrinal, but many Axis units come with STGs.
Flaming stick grenades didn't exist, but Soviet need a doctrinal unit to have access to any sort of grenade period.
Most king tigers were abandoned, but it's the Americans that can bail out not the OKW.
Is-2 out produced King tigers but one is in only 2 doctrines and the other is in every single doctrine okw will ever get...
I'm starting to think this game is only loosely based on history and not actually a military simulation based solely on historical production numbers but I'm not sure. I'll keep doing research and get back to you.
