If I have 5 turns left before the deadline for the brilliant victory, and I go ahead and win it, do I potentially lose out on some prestige? Should I just station my troops around the last area and just camp it out till the last brilliant victory turn so I get the most amount of prestige?

Ok this question is dumb af. Idrc about the answer to that one, but can someone fr answer this: 

What German units are engineers? I've read that engineers are able to bypass fortifications and directly do damage. Is there any indicator as to which units these are? Idk German so everything's been tough.

I think Brukenpioneere are engineers + bridge. There are some other infantry units with engineer flag, something that I need to improve is how to display that.

If you do brilliant victory faster you might lose some prestige per turn which some scenarios award every turn. Also make sure you take all secondary objectives and kill as many enemy units (for experience). I usually do tactical for the first few scenarios just to train core units.
