Personaly, I think my 2 favorite weapons would be the Gewehr and the Lee End Rifle. I believe the Lee End was the most produced gun. For planes, I'd say B-17 and F6F-5 HellCat, even though it wasn't used too much. Tanks would be T-26B, because it kicked Germany's arse when they tried to invade Russia. It just had the right technology to make it through the snow, and since the German's tanks always got stuck, their infantry was, well, screwed. They wern't prepared for the weather either.
