I'm going to assume that you meant "trenches". They were used to protect soldiers from artillery and/or strafing and bombing. Also they provide cover from enemy fire. Which is harder to shoot, somebody's head or somebody's whole body? They used them in World War two also. It used to be (civil war era) that the opposing sides would just run at each other and shoot. When machine guns were invented that tactic became obsolete. If you watch crime shows then you will see when the cops are getting shot at they duck behind a car or a crate for cover and then when they shoot they just stick their gun and half of their head out. It does the same thing as a trench, but military trenches also defend against artillery and bombs.
