Geography and Industrialisation..

This was the first modern war that was fought between two highly industrialised nations (and their allies) where the geography of the Western Front permitted both sides to relatively easily pour all their resources into it at will.

The three technologies:

Modern communications ie the trench telephone system and the telegraph plus to a lesser extent, "wireless"

The Machine Gun

The Tank

Edited to add the U-Boat..perhaps not directly affecting the Western Front but in a wider sense it was a strategic weapon for the Germans that almost won them the war..
