Some questions regarding the game

[nuNce]

Hello there,
I've bought the game a few days ago and I'm loving it. I've played SPWaW before, but since I couldn't run it on linux I had to abandon it, but I don't have regrets!

I have two questions for you. The first is about artillery. I've noticed that after a strike, sometimes my planned hex has moved away into another one. Why is this?

The second one is about the scenario nr 2, Stonne. I'm finding out that the German troops are almost bulletproof, while my frenchies are a couple of greens. The jerries even fight back tank fire withot fear. While I understand that this are SS troops, while mine are French army's 1940 troops, my question is: is it supposed to be like that or am I doing something wrong? Thanks!
