I wanted to make an Ostwind agaisnt P47 but then I realized that Ostwind is better at killing infantry than planes... So in fact as OST I have no counter play agasint P47.
Ostwind at vet2 gets anti air boost .. So getting an early ostwind and keeping it alive will help against late game P47s.. it takes a lot of time to vet it up to 2 stars though..
Ostwind will come out a couple of mins before sherman and become useless on frnt line after Jacksons hit the field so somewhere in between if you can manage to vet it up its gonna help a lot agasint those thunderbirds.. ( Tiger ace doc should help)
