]FIG. 52a.--Dug~out under 10 feet of unzdistuibed earth. Maximnum depth
to be cxecuted 2O feet.
The dugout is therefore, in the absence of' some other control­
1ing factor, the absolute rule. It ought to be undertaken wzi~thout
delay by the infantry itself, unde~r the direction of the
regimlental and company pionee s, without awaiting the a'ssistance
of engineer troops. Every officer and noncommrissioned
officer ought to know' in detail the simple normal type represented
in fig~ures 52 and 52a.
The chart~.acter~istics of th~e nornmal dlugout are:
1. They are located under at; leazst 20; feet of unt~isturbed3
earth. Eighteen feet of hard compact chalk resists larg~e mine
shell and heavy shell with delayed action fuse. Fiigure 52 represents
a shelter -with only 10-foot cover; it is easy to ima~gine
it dleeper.
