qqp question1: WW1 was mostly trench warfare. What were battlefields like in WW2? I know trench warfare didn't happen due to more advanced technology, but what were the areas of battle like? Where they on fields, towns or hills? What were the frontlines between the two sides? question2: Why wasn't WW2 like WW1? Why wasn't trench warfare used? Was it because of the development of the tank?
