Why didn't battles in WW2 ended up soldiers digging trenches and charging at each other like WW1?

Hiya!

This is a variation on one of our frequently asked questions, and a lot of fantastically written responses have addressed it in the past. Hopefully, some of these will point you in the right direction.

Warfare tactics changed greatly between World War One and World War Two; when and why did this occur?

How different was manoeuvre warfare on the WW I Western Front in 1914 vs late 1918 ?

Why was World War 2 more mobile than World War 1?

If you have any specific questions, I'll happily do my best to answer them! :)
