Good questions Koba interested in hearing the official answer.
Just for the record, we place the pars at the beginning of Russia’s turn. If there was already a par in that territory (meaning it is still unoccupied by axis) then we replace it with a Russian inf and Russia takes control of it (at the very beginning of Russia’s turn). I’m not sure if that reverted Russian territory would be an eligible landing spot for Russian air units (later in that same turn), but because we make that transition before Russia’s combat moves, I would say yes.
Being that one par doesn’t revert control of the territory back to the Russians, I think that it wouldn’t block axis movement, and that axis air units would be able to land. In my mind pars would be more of a nuisance disrupting things in small pockets, but the Germans would still hold the air strips and they’re not going to stop a panzer division.
Edit:
We have killed off the pars as Germany in the past, but you bring up some good points. It does have a def value of 2, so it very well could block combat moves, and if not killed off could stop axis air units from landing.
If your using supply line, or rail (which we haven’t done), I would think a par could disrupt them.
I think that pars are very important to the Russians as a whole. They do a couple of things. Axis having to leave inf in each occupied red territory means fewer inf to attack with in the end. Even though they can continue moving forward as they bring in inf reinforcements, it’s still a slow process and they’re not buying faster mechanized units. The axis may even skip some red territories because they don’t want to strand inf behind. That could help Russia’s allies coming to the rescue having a place to land air units etc…
We were thinking that if a par is placed in say a Russian territory captured by Germany, and the par is still there in Germany’s collect income phase they shouldn’t be able to count the income for that territory (if it has income value) because they don’t have total control of it. Kinda like a penalty for letting it happen.
