Non-commissioned officers are held responsible for a systematic and orderly execution of the work being performed by their units. The captain cannot be everywhere along the line. He has to depend upon the platoon and squad leaders in the work. That is why you should study it and know about it so as to be able to make good when the time comes.
Chapter VIII
GRENADE WARFARE
The use of hand grenades as an implement of warfare dates back many centuries. History records their use as far back as 1536. Up to the close of the eighteenth century soldiers were trained in the throwing of hand grenades, and for this reason were called "grenadiers." At first there were a few in each regiment, later entire companies were formed, and finally each infantry unit that corresponds to our battalion of today had its own grenadier unit.
Then there was a period of time when more open formations were adopted, when there was less opportunity for the employment of grenades and their use was practically eliminated from the battlefield and confined to sieges, where they have been used more or less since the dawn of military history.
With the advent of the Russo-Japanese War came the extensive use of trenches on the battlefield, and with the trenches came the hand grenades which were used in large quantities by both sides. This was especially the case when the fighting lines came to close quarters and in the assaults against the forts at Port Arthur.
When the European war resolved itself into trench warfare, such as it is today, the use of hand-thrown projectiles assumed an importance heretofore never attained, and today we find ourselves employing hand grenades in every phase of the conflict.
