A soldier pile wall using reclaimed railway sleepers as lagging. Soldier piles, also known as king piles or Berlin walls, are constructed of steel H sections spaced about 2 to 3 m apart and are driven or drilled prior to excavation. As the excavation proceeds, horizontal timber sheeting (lagging) is inserted behind the H pile flanges.
Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles, sheet piles, secant and tangent walls) to provide additional stability to cantilevered retaining walls. [1]
Larssen sheet piling is a kind of sheet piling retaining wall. Segments with indented profiles (troughs) interlock to form a wall with alternating indents and outdents. The troughs increase resistance to bending. The segments are typically made of steel or another metal. [1]
Earth ditch and rampart defences on the Ipf near Bopfingen, Germany Reconstructed pfostenschlitzmauer of the oppidum at Finsterlohr, Creglingen, Germany. The composition and design of ramparts varied from the simple mounds of earth and stone, known as dump ramparts, to more complex earth and timber defences (box ramparts and timberlaced ramparts), as well as ramparts with stone revetments.

A total of 5,754 piles were tested and 2,955 failed more than one fifth of an inch. Roughly 1,700 piles were subsequently spliced and re-driven an additional 10 to 20 feet. The pile driving was finally complete in 1851 and the wooden grillage was the next layer constructed. [21]
In this way, a soldier can improve the position over time, while being able to stop at any time and use the position in a fight. Typically, a DFP is a pit or trench dug deep enough to stand in, with only the head exposed, and a small step at the bottom, called a fire step, that allows the soldier to crouch on to avoid fire and tank treads .
