Sorry, by advance, for my poor english, I'm french.
I'm playing a campaign as soviet, we are at the 19° turn. My adversaire had stopped attacking till the 15°turn and he started building some fortifications and now we have a front like this:

I have nerver play the blizzard attack before and I ask me which is the best method to destroy the forti level 3
I know usually people put 2 sappers and a tank bn in their cavalry corps.
But in this case isn't a good idea to add one 230mm (siege) art with the sappers ??
Maybe just put some of them in my HQ ?
I know, it cost a lot armement pt and ammo.
My state of ARM production

P.S I don't understand why only 247 factories produce and not 352-26= 326[&:]
