Easy Way To Defeat Von Schrauder:
During this mission you get a lot of M9 bazookas. The trick is to keep them with until the fight with Von Schrauder. As soon as the fight begins kill the first wave as Von Schrauder does not appear for a little while. After the first wave is gone neglect all of the others. Take out your M9 Bazooka and aim at him and fire. He should die in about 2-3 shots if hit correctly.

Escape To Dawn: Hidden grenades
When your on the last level of the first attacks and the Panzer comes through the wall, let it blow up the mini houses. When they are blown up, get the grenades in them. If you get enough of them, you can blow up the Panzer. Keep throwing the grenades; it takes awhile.
