be impressed upon him that, in taking advantage of natural
cover, he must be able to tire easily and effectively upon the enemy;
if advancing on an enemy, he must do so steadily and as rapidly as
possible; he must conceal himself as much as possible while firing and
while advancing. While setting his sight he should be under cover or
lying prone.

153. To teach him to fire easily and effectively, at the same time
concealing himself from the view of the enemy, he is practiced in
simulated firing in the prone, sitting, kneeling, and crouching
positions, from behind hillocks, trees, heaps of earth or rocks, from
depressions, gullies, ditches, doorways, or windows. He is taught to
fire around the right side of his concealment whenever possible, or,
when this is not possible, to rise enough to fire over the top of his
concealment.

When these details are understood, he is required to select cover with
reference to an assumed enemy and to place himself behind it in proper
position for firing.

154. The evil of remaining too long in one place, however good the
concealment, should be explained. He should be taught to advance from
cover to cover, selecting cover in advance before leaving his
concealment.

It should be impressed upon him that a man running rapidly toward an
enemy furnishes a poor target. He should be trained in springing from
a prone position behind concealment, running at top speed to cover and
throwing himself behind it. He should also be practiced in advancing
from cover to cover by crawling, or by lying on the left side, rifle
grasped in the right hand, and pushing himself forward with the right
leg.

155. He should be taught that, when fired on while acting
independently, he should drop to the ground, seek cover, and then
endeavor to locate his enemy.

156. The instruction of the recruit in the use of cover is continued
in the combat exercises of the company, but he must then be taught
that the proper advance of the platoon or company and the
effectiveness of its fire is of greater importance than the question
of cover for individuals. He should also be taught that he may not
move about or shift his position in the firing line except the better
to see the target.

_OBSERVATION._

157. The ability to use his eyes accurately is of great importance to
the soldier. The recruit should be trained in observing his
surrounding from positions and when on the march.

He should be practiced in pointing
