In selecting a target and opening fire it must be remembered that the fire cannot have a decisive effect unless the target is well within effective range. The leader should ask himself whether the result to be expected is properly commensurate with the probable expenditure of ammunition entailed, and whether this expenditure is warranted in view of the total amount available. But the decision to fire upon a target once made, the ammunition necessary for the attainment of the object of the fight must be expended without stinting, since all experience teaches us that an ineffective fire impairs the morale of one’s own troops, while it raises that of the enemy. In the selection of a target, its tactical importance is the principal determining factor. The fire is first directed upon the most dangerous, generally the nearest target, or the one which is soon to become the most dangerous. Subsequently the fire should be directed upon targets which, owing to their height, width, depth, and density, promise the greatest number of effective hits. Infantry will, as a rule, offer the most important and promising target, and the fire should be directed against the firing line, since the troops following it in close order will in any event come within range during their advance. In Italy, when two targets are available, the fire is to be directed on the one promising the best results. Ballistic and tactical considerations determine whether fire should be opened at long or at short ranges. Adequate results may be expected when the fire is directed against low targets at ranges of 800-1200 m., but at ranges over 1200 m. a decisive effect is only attainable by the expenditure of a large amount of ammunition. Skirmishers standing may be fired on with good effect even at ranges over 1200 m. (long ranges). When the fire is properly controlled and directed, it will be effective against tall and deep targets within ranges corresponding to the highest graduations of the rear sight leaves. However, when the targets are narrow, a side wind is very apt to throw the cone of dispersion off the target.
