Jennifer is right re: attack Russian territories with Italy/reinforce with Germany.
Here’s why, as I’ve spelled out in a few other places:
1. Italy gets the IPCs. This helps to keep them a viable force.
2. Germany reinforces. Germany loses no Infantry in this transaction.
3. The Italians who originally took the territory are still alive. Russia does not get a chance to kill them.
4. Repeat the next round.
I recently did this against a good Allied player. Italy routinely collected 25+ IPCs, with no territories held in Africa. I don’t know about anyone else out there, but I thought that was a big deal. Germany was still collecting in the low to mid 60’s, and that number climbed as NOs were obtained. By the end of the game, most of Russia was in Italian hands, with the exception of Leningrad, Moscow, and Stalingrad, which I greedily avoided to allow Germany to take and hold, to allow them the ability to replace Infantry on the front.
Typically in a slugfest between Germany and Russia, Infantry on both sides pay the price. What I found was an amazing capacity, using this method, to almost never lose German land units. It was a slow and deliberate, methodical grinding down of Russia.
Thank you Italy. I heartily disagree with anyone who contends that Italy is a useless power, or that once kicked out of Africa they become a useless power… on the contrary - they are vital to success.
