2nd. To teach him how to throw them.
3rd. To make him acquainted with the general principles of
organization and the execution of a grenade attack, either as a
separate operation or as a part of a general attack. The time spent on
any such course of training is a matter to be settled in the light of
local considerations; but for purposes of preliminary training of a
great number of men a period of two weeks is usually sufficient, with
time allotted according to some such plan as this: (1) 10 separate
half-hour sessions of practice in throwing from various positions and
at the various targets; (2) 2 hours of study and a like amount of time
spent in a conference for the purpose of clearing up matters that are
hazy. In this brief time (only 9 hours) the foundation may be laid for
a more thorough training of the specialists later on. In any such
course the use of dummy grenades should always precede the use of any
live ones; and men should be taught caution above all other things.
This is a point easily lost sight of when men are using only dummies;
but it is well worth remembering, for obvious reasons.

FIRST: GIVING THE INDIVIDUAL A PRACTICAL KNOWLEDGE OF THE WORKING OF
THE GRENADES IN USE.--The differences in the construction and the uses
of hand and rifle grenades should be brought out clearly. The various
sorts of grenades should be explained and men should not forget the
importance of knowing the grenades of the enemy as well as our own.
This knowledge may one day prove of no little importance. As has
already been stated, the Mills No. 5 is the standard among hand
grenades of the Allies. It conforms to the general description of hand
grenades; _i.e._, it is an egg-shaped projectile, more or less hollow,
and loaded with a charge of explosive. Besides this it has an
apparatus for setting off the bursting charge. It weighs 1 pound 5
ounces approximately, and 4 ounces of this is high explosive. The
shell being of serrated cast-iron, an explosion will scatter a sort of
shrapnel over an area equal to three times the height. No more need be
said of the effectiveness of such a weapon. Among rifle grenades the
Mills is also the standard more or less, although the French make
great use of a rifle grenade that fits over the muzzle of the rifle,
fired by ball cartridge, in contrast to the Mills No. 23, which has a
rod running down the barrel of the rifle and which i
