extra ammunition as may be received
from the rear. (I. D. R. 249.)

Having indicated clearly what he desires the platoon leaders to do,
the captain avoids interfering, except to correct serious errors or
omissions. (I. D. R. 240.)

=1436. The Platoon Leaders.= (_Fire direction._)

In combat the platoon is the _fire unit_. (I. D. R. 250.)

Each platoon leader puts into execution the commands or directions of
the captain, having first taken such precautions to insure correct
sight setting and clear description of the target or aiming point as
the situation permits or requires; thereafter, he gives such
additional commands or directions as are necessary to exact compliance
with the captain's will. He corrects the sight setting when necessary.
He designates an aiming point when the target cannot be seen with the
naked eye.

In general, _platoon leaders_ observe the target and the effect of
their fire and are on the alert for the captain's commands or signals;
they observe and regulate the rate of fire. (I. D. R. 252.)

=1437. The Guides= watch the firing line and check every breach of
fire discipline.

=1438. The Squad Leaders= transmit commands and signals when
necessary, observe the conduct of their squads and abate excitement,
assist in enforcing fire discipline and participate in the firing.

Every squad leader should place himself just a little in advance of
the rest of his squad and by occasionally glancing to the right and
left, observe how the men of their squads are doing--whether they are
firing at the proper objective, if the sights are apparently properly
adjusted, if they are firing too rapidly, etc. After each shot the
squad leader should look toward his platoon leader, and then glance to
his right and left to observe his men, and then load and fire again.

=1439. The Musicians= assist the captain by observing the enemy, the
target, and the fire effect, by transmitting commands or signals, and
by watching for signals. (I. D. R. 235.)

=1440. The Privates= will take advantage of cover, exercise care in
setting the sights and delivering fire; be on the constant lookout for
orders from their leaders; always aim deliberately; observe the enemy
carefully, increasing the fire when the target is favorable and
ceasing firing when the enemy disappears; not neglect a target because
it is indistinct; not waste ammunition, but be economical with it; if
firing without a leader to retain their presence of mind a
