It remains to mention briefly the effect of ricochets which, as a rule, tumble[1] after striking. Their range upon rebounding is short. Bullets ricochet most frequently on water, on rocky and hard ground, more rarely on wet meadows, and on tilled soil, but they do not ricochet at all on sandy soil. Ploughed fields, in which the furrows run obliquely to the line of fire, eliminate the effect of ricochets almost entirely. When jacketed bullets (but not the massive French "D" projectiles) strike upon rocky ground, they have a tendency to alter their form materially, or to tear the jacket, thereby considerably increasing the severity of the wound which is produced. The range of ricochets upon rebounding depends mainly upon the angle at which they are deflected. When the lateral deflection is 30 degrees their range may amount to about 1300 m. The nearer a bullet strikes to the skirmisher firing it, and the smaller the angle of deflection of the consequent ricochet, the greater its range; under favorable conditions this may amount to 2500 m. According to French experiments, in firing at a range of 800 m., 4% ricochet hits struck a target, the height of a man, at 1400 m., and 1% ricochet hits a similar target at 1850 m. from the skirmisher who did the firing.
13. LOSSES IN ACTION.[2]
An attempt to move troops in close order formations within the zone of uninterrupted infantry fire at ranges under 1500 m. when the enemy is still in condition to direct his fire on them, is bound to lead to losses which make the further tactical employment of these troops impossible.
Bodies of troops following the firing lines will also have to deploy when the hostile fire reaches them, unless they can find cover. It is a disadvantage for them to deploy, and every opportunity to return to close order formation must be utilized.
