When fighting in a trench against an enemy, the front side (facing the enemy) of the trench is called the parapet and the rear side is the parados. In the world wars, the parados was built up higher than the parapet to prevent the soldiers from being silhouetted against the sky behind, making them easy targets for German snipers.
