did any of you use paratroops?
Yes. I used them in my attacks on Leningrad and Moscow. I also used them to try to close a few encirclements. Several times, if a big group of Soviet divisions was retreating into an empty province, I would try to land an airborne division there to capture the retreating divisions. (In AoD if unit reaches the province it is retreating to, and that province and the province it was retreating from both have enemy divisions in them, then the retreating division is destroyed). However, I only had 2 airborne divisions and it takes a long time for them and the transport planes to regain org. You have to be very selective about where to use paras, and it can be dangerous. During the course of the Barbarossa campaign, both of my airborne divisions were shattered/destroyed, meaning that I did not have any left when I did SeaLowe. Airborne forces are a big investment of IC, manpower, and tech research. They can be quite useful but I am not sure if they are worthwhile.
i heard gringo you have 3 marines (for the pripet marshes?) and 3 were sunk on their way to suez.
I used the marines for doing amphibious assaults on Suez (big mistake on my part), Riga in Latvia (to close a big encirclement), Leningrad, and SeaLowe. I also used the marines in the swamps of southern finland and northern russia after Leningrad had fallen.
did you also put all your mountaineers into finland?
I kept all five of my mountain divisions in Norway and used them to repel Allied amphibious landings. The British and Commonwealth forces made several landing attempts. I did not protect the beaches; I let the enemy land and then pushed them back into the sea, thereby annihilating the entire landing force.
