These should lie above and beyond the target and in line with it. It goes without saying that an aiming point fulfilling all these conditions will rarely be found. Moreover, the aiming point must not be selected at random at some particular elevation, because the angle between target and aiming point, expressed by graduations on the rear sight leaf, might possibly lead to a negative sight setting. “In the practical tests made on varied ground against targets of appropriate height, splendid results were obtained as regards effect; but the aiming point had to be indicated by means of a flag. Despite the fact that the terrain was covered with numerous objects, such as trees, woods, factory chimneys, etc., no suitable aiming point could be found on the terrain itself. This largely determines the value of indirect rifle fire in the field.” This class of fire is, however, worth a trial at any rate. Moreover, its tactical, combined with its moral, advantages are so great that we could afford to accept calmly a fire effect poorer by comparison. Indirect rifle fire will, at times, give troops an opportunity to do damage to the enemy without being themselves seen or fired upon.
