March the even-numbered
squads stand fast while the odd-numbered squads form the
first line by deploying on the base squad as in the case of
deployment in single line. Similarly, the even-numbered
squads form the second line by deploying on their base squad
after the odd-numbered squads have moved forward about 20
paces.

D. Being in line or column of squads to deploy in line of squad
columns in one or two lines. Use same commands and execute in
same manner as described in (A), (B), (C), except that in the
command "Squad Columns" is substituted for "as skirmishers,"
and in the execution each corporal on approaching the line
forms his squad in "squad column" instead of deploying it as
skirmishers.
_E.G._ 1. In two lines--2. Squad columns (so many) paces, Guide
right (left or center)--3. March.
This gives a "Formation of Approach" as the French describe it,
or as an "Artillery Formation" as the British describe it; which
may be used directly or indirectly (by means of echelons) for
advancing when not liable to infantry fire.

E. Being in above formation to vary the intervals.
1. Squad columns (so many) paces, 2. Guide right (left or
center). Executed in the same manner as similar movement
described in i.d.r. 126.

General Principles of the Platoon Formation in the Assault of
Fortified Positions in Trenches. (Points of Resistance, Etc.).

1. The platoon is now a complete fighting unit within itself. It
contains riflemen, bombers, auto-riflemen, and rifle grenadiers. With
this combination the platoon commander has, under his immediate
control, all the different kinds of fire available to the infantry.

[Illustration: Plate #23]

2. This formation was developed so that the platoon commander could
meet the different contingencies that arise from being opposed by
points of resistance in a "Trench-to-Trench" attack or the
"Semi-Open-Warfare;" that is the secondary stage of a push.

3. When strong opposition develops, the principle on which the platoon
works is to develop or surround the point of resistance, the platoon
acting either alone or in conjunction with neighboring platoons. The
four different kinds of fire are then used to their best advantages to
silence or diminish the
