Soldiers who were new to the trenches of World War I quickly learned their way around the trench system. All of the trenches were dug with a main trench against the front line and several support trenches behind that. The formulaic nature of trench construction made it fairly easy for soldiers to find their way around.

support for earth, Generally consists of shuttering boards or drag boxes made out of metal which get gragged along the trench as and when they finish with them. It also depends on the depth of the trench.
Between 70 and 100 yards (64-91 m) behind the front trench was located the support (or "travel") trench, to which the garrison would retreat when the front trench was bombarded. Between 300 and 500 yards (275-460 m) further to the rear was located the third reserve trench, where the reserve troops could amass for a counter-attack if the front trenches were captured.

During World War I, "support trenches" were found throughout the theaters of the war wherever trench-lines were constructed. Running perpendicular and parallel both to the main defense-line trenches, support trenches enabled front-line troops to communicate with each other, receive supplies, and organize for coming battles without being in the line of fire of the enemy across the (often quite narrow) "no man's land" between enemy lines.
