Not bad.
To IceDragon64:
The Tank is a Panzer II, and had a rapid fire cannon, as depicted in this Flash, and it blew up because it was hit by an Anti Tank (AT) Rifle, designed to destroy armor.
I need to agree with you that it appears that the Ju87b Stuka was 'not in this Flash', mainly because you only see a cockpit of a German War plane, could be BF109, so I can't tell.
To submit 1:
I can agree with the lack of designs on buildings and the background, though the units are fine by me. Humor though is not important here, because (at least I think so) this Flash is more of a documentary, or a flashback (no pun intended) of the Eastern Blitzkrieg.
To both:
Argh! Isn't obvious of who is who? A Polish flag is shown at the Preloader, and the dark grey sticks were the Germans, and the light grey sticks were the Polish. Simple!
To Stick-Corporation:
Not a bad Flash, but there are, as stated above, some parts which could've been improved: 1, the Germans seemed the only ones who died and were losing. Shouldn't it be the other way around? 2, the German's helmet is not of the correct design, it seemed more like the Polish's helmet. Other than that, it is good!
