[1146]. Standing trench ([Fig. 4]) has a bottom width of 3 to 31/2 feet and a relief of 41/2 feet which is the proper firing height for men of average stature. As this trench does not give complete cover to men standing in it a passage way should be constructed in rear of it not less than 6 feet below the interior crest. This forms the complete trench ([Fig. 5]). [Figures 6]–[7]–[8] show simple standing trenches used in the European War.
