Anonymous, Lectures on Land Warfare; A tactical Manual for the Use of Infantry Officers
“ GRENADES.—Hand grenades and rifle grenades are adjuncts to the rifle and bayonet and the Lewis gun. Their principal use is in clearing fortified posts, especially in Position Warfare. The hand grenade, or bomb thrown by hand, is limited in range by the skill and strength of the thrower, and 30 to 40 yards may be regarded as the maximum distance. The rifle grenade is effective up to about 400 yards, and is generally employed to provide a local barrage or to search cover. In the latter case, a high angle of descent is used as with mortars or howitzers. ”
