Parados

...an elevation of earth which is effected behind fortified places, to secure them from any attack that may be made in reverse. Parapet and parados come from terms signifying in the front or in the rear of anything.

Although a parados takes up so much room, yet it may be turned to good account in the formation of blindages.

In an enclosed work the interior can seldom be sufficiently covered from the enemy’s fire by the parapet, and it becomes necessary to build traverses or parados or both. The parados is only a large traverse built inside the work to cover the defenders who stand on the faces or flanks furthest removed from the enemy’s fire

He stood up on the step; and then they both swerved, ducking quickly as something ripped up the air between them, flicked a stone from the parados, and sang, like the vibration of a tense wire, into the air behind them.

The 1940 manual viewed the foxhole too as a hasty position, a simple one-man hole about 3 feet in diameter at the top and 2 feet at the bottom dug suitably deep for crouching, kneeling, or standing. Earth was thrown to the front (parapet) and rear (parados) in crescents. (The term "parados" fell from use in World War II being replaced by "rear parapet".)
