The Great Wall of China or Hadrian's Wall, were exceptions to the general rule and were in any case not designed to completely prevent entry of enemy troops, but simply to make it difficult for the invader to mount a penetration in strength. The Great Wall of China or Hadrian's Wall, were exceptions to the general rule and were in any case not designed to completely prevent entry of enemy troops, but simply to make it difficult for one army to break another by a direct assault.

Trench warfare is a form of war in which both opposing armies have static lines of fortifications dug into the ground, facing each other. What made this tactic increasingly suicidal was the introduction of mass-conscripted armies during the Battle of Gettysburg, revealed the military futility of a direct assault on an opposing line.
