I understand that medieval combat was basically men with swords running at each other, WW1 combat was basically men in trenches, but what was WW2 combat like? The only exposure I have to the subject is from WW2 films, which usually show a group of 10 guys with machine guns running around the German countryside until they find opponents, and then using whatever cover they could find and engaging the enemy. Is this an accurate representation of the average combat? It seems like an army of tens of thousands wouldn't just split up in groups of 10 and run around aimlessly.
