Not really, I was given Soviet equipment and just got more as Poland was meant to be the 2nd Echelon in either an offensive into NATO territory or the 2nd echelon of defense.

You still lack a way to counter the IS-3 and Russian air superiority. The former isn't such a major thing. The latter /is/. I wouldn't put it beyond Russia to start bombing Polish cities if they get bogged down. You're not Afghanistan, you do not have the US as your friendly weapon-providing friend. Once you piss Russia off, that's /it/. You cut off your own weapon supply, and are suddenly surrounded by people who really do not like you.
