The trench between the front line and the support trench was called a "communication trench." These trenches were crucial for enabling the movement of troops, supplies, and information between the front lines and support positions while minimizing exposure to enemy fire. Communication trenches were often zigzagged to reduce the risk of being hit by enemy artillery.
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.

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.
There is no scientific evidence to support the existence of Atlantis, so it is unlikely to be at the bottom of the Mariana Trench. The Mariana Trench is a deep oceanic trench, and while it is a remote and largely unexplored area, there is no indication that it could be the location of a mythical lost civilization like Atlantis.
