Note 10 — Chapter VI · FIELD SERVICE.

Figure 5 shows the plan of a section of a rifle trench.[10] Between the portions occupied by each squad there is often placed a mound of earth as high as the top of the parapet and projecting back into the trench. This is called a traverse and protects the occupants of the trench from fire from a flank. Bullets from this direction hit a traverse, instead of flying down into the trench and wounding several men.
