Dangerous Space

That zone, partly before and partly beyond the object fired at (the sights having been correctly elevated), which is covered by the trajectory; the object may be displaced to the front or rear of its correct range-point, a distance equal, in the aggregate, to the depth of this zone, and still be struck by the projectile. “Dangerous space” is calculated under the a umption that the gun when fired is 56 inches from the ground, that it is aimed at a point 34 inches from the ground, and that the stature of a man is 68 inches; and that the head of a man on horseback is 8 feet above the ground. The “dangerous space” will, of course, be increased by the firer lying down and aiming at his adversary’s feet. A part of the “dangerous space” is near the muzzle of the gun in the rising branch of the trajectory; the rest of it is in the falling branch; these two parts being continuous up to and including the “ battle-range ” (which see). The “dangerous space” varies with the weapon used and the object fired at; and for the same arm diminishes as the range increases beyond “battle-range”; up to this point it increases with the range. A perfect understanding of this subject is e ential to effective infantry fire upon the field of battle. Valuable tables will be found upon it in Laidley’s “Rifle Firing.”
