Here you can see a bad attacker.

He is doing almost everything wrong.

The only thing he is doing right is that he has supply. If you see an army with a red fuel can can icon, it means they have no supply and fight like abysmall garbage.

an orange fuel can is okay.


Here you can see a pretty good attacker.
He forgot to use air support though, and he is using the really bad tank templates that germany starts with in the 1939 scenario. Poland is so weak he wins easily anyway though.

The attacker spreads out their defensive units evenly on the green field marshal line, and concentrates their attacking units in a small area (with enough supplies) on the red front line.
