Either digging strait down and creating a new trench, or adding on to existing trench systems already created. The first way is very fast but you are able to be shot while digging the trench so it make this a risky style of building the trenches. The second style is much safer but only works if you have existing trenches you can extend in your location. This style keeps you out of the line of fire from the opposite trench because you aren't up in no-man's-land trying to dig a trench. These trenches were roughly three meters deep and one to two meters wide. These would have sand bags in front of them. They didn't always fill them with sand, they sometimes filled the bags with dirt that was dug out of the trenches. They would be protected by barbed wire in front of the sandbags to help deter and slow enemy attacks. These trenches worked as great protection from enemy attack, especially for moving troops. These trenches worked as protection from enemy fire because it gave a great place to hide from attacks. Although this would lead to the use of mortars, grenades, and gases. They would also evolve into tunnels that would go under enemy trenches to either move troops or to also attack other trenches by placing explosives under the trench. They would use underground mining machinery but would do it as quietly as possible for fear of the enemy hearing what they were doing and planning a
