I’ve been using the Wrus attack only for at least 6 months now and have yet to see real problems with it. I’m not saying there aren’t draw backs but I have seen anything that is fatal to the Allies.
You CAN hold both Cauc and Wrus with the Wrus attack only.
I’ll attack with 9 inf, 2 rt, 2 arm, 2 ftrs. This essentially kills Wrus in 1 rd and you’ll lose 2 inf at most.
If I lose 2 inf, I’ll move the last inf from Kar for the extra defense. With 1 hit, I’ll leave the blocker in Kar.
So I’ll have:
Wrus: 8-9 inf, 2 rt, 2 arm, aa
Cauc: 7 inf, 3 arm, 2 ftrs, aa
Rus: 4 inf, 2 arm
Germany has to commit too much and does too much damage too themselves if they attack/strafe either target. Even if they take one they get slaughtered on the counter.
Oh yeah, this is with no units bid to Europe.
This, may not be the best setup and I don’t know the odds of the German attacks, but I do know no one has yet to test those German attacks.
Worst case for Russia (3 hits in Wrus), you can stack everything in Wrus and deadzone Cauc.
As Frood pointed out the one turn of 4 IPC is not that big of a deal. You can even leave 2-3 inf in Cauc and see if Ger commits a tank, otherwise you get to kill probably 2 inf, 1 rt and maintain a heavy stack in Wrus and Cauc on Rd 2. Since Ger can’t attack Cauc on Rd 2 (well they can send 2 units from a trn and maybe a couple planes, but that won’t be enough)
