What if OST T4 building provides vet1 to all squads. Like what wermacht had in CoH1 as vet techs.
Coupled with that, pio vet1 could be changed to +10% dmg reduction. Med kids are not worth it.
Two birds w/ one stone. A worthy T4 buff+Pio late game presence
That's a tricky dog because then vet 2 is closer and vet 3 as well. Bought vet as a whole is not ideal. I'd sooner (personally) for t4 to give ost infantry a 10% damage reduction independent of vet, and might as well throw them skirts on their tanks as well. Replace vet 2 with something else (maybe + range for the stug?) this improves ost infantry when they need it most and makes t4 attractive even with a t3 build
