Partisan Resistance
When the Wehrmacht rolled into the Soviet Union in World War II, it got more than it bargained for. Soviet citizens fought fiercely against German occupiers, engaging in raids, sabotage, and intelligence gathering.
You may end the battle after first round of combat when you attack, and stay in the same territory as the enemy. These units are locked in combat and can not move out of this territory before the opposing force is destroyed.
This last NA would let a minor Russian infantry-corps attack a larger German panzer army, and if some russians survive, they can stay in this territory and lock the panzer-army in combat. There are historical reasons to back this rule up. Since most Russian territories had forests, swamps, mud, dirt-roads only, and a long cold winter, it was easy to bug down the German advance. Russian units would hide in the forest, let the German panzers through, and then close the gap and do ambush-attacks. Also the russian winter would kill more germans than the bullets. Half of the attackers would freeze to death, or be sick from frostbites and cold desies, just like Napoleons Grande Armee 100 years earlyer.
Do you think this is a better NA than Rasputista or should I replace it with any other NA of Russia?
Rasputista
With heavy rains the landscape changed in a blurry mess of mud where vehicles and men got stuck and were unable to advance.
Once during the game in your collect income phase, you can declare a Rasputista. Until the start of your next turn, no combat movement for land units is allowed in any red territory.
