@Octopus:
There is a huge difference between an infantry and an AA. The difference is, the infantry can be destroyed…
Someone mentioned the idea of capturing the gun…except a solid Russian strategy is to not bother defending both zones that protect Russia (Belorussia and Eastern Ukraine). A single mass of units exist in one zone (along with an AA), while only the AA exists in the other. If the Germans try to capture the gun, they will be taken by the mass in the other zone.
The use of the AA to block the blitz allows the Russians to protect both zones effectively while only occupying 1 zone and risking no units.
Sorry Octopus, but the huge difference is that infantry has a chance of killing a panzer. AA just gets captured. It doesn’t even provide air cover for Moscow since it doesn’t fire on moving AC.
IMHO this does not appear to be a solid Russian strategy.
Besides, if you make a House Rule saying the AA doesn’t block a blitz then the Russian would produce the same cheap road block - actually a 2 IPC cheaper one - that also fights back by placing a single infantry in the non-stacked space. At least that way they get a 1:3 chance of killing a panzer rather than leaving my thrust untouched.
