Lots of people like to try to overpower Egypt with mass forces, like Darth or Akreider. That makes it difficult if Ukraine is attacked since now not only do you have to overpower Egypt (try your best to one shot Egypt), but retake Ukraine and kill the UK BB off of SZ13. You’re probably going to lack fighters in Ukraine which means thinking about saccing a tank, which is ugly. 3 figs to the UK bb with a sub, 1 fig to hit the destroyer or Egypt which is a tradeoff already, and you have 1 fig + infantry to take out the 3 arm + in Ukraine (btw it’s 62% according to frood to take Ukraine with 3 arm or better, and 90% to take it with 1 arm or better…)
And if you don’t overpower Egypt, then you can forget about making any progress in Africa unless you purchase something big in the med, which you can’t really do if you’re replacing the fighter you lost.
It’s best to assume that 3 arm will occupy Ukraine, because that or better happens an obvious majority of the time. In that case remember that those 3 arm are taking out units on their way out and spreading Germany’s attack pattern thin if they’re also taking Egpyt and the UK BB.
Good luck favors the Russians more in Ukraine than the Germans, I think. Even with some crappy luck then Russia has at least cleared Ukraine, which you’re already assuming as a worst case scenario which happens less than 10% of the time, but if the Russians hit the other end of the spectrum you’re seeing 1 art 3 arm in Ukraine, which overtaxes Germany’s coping resources.
