German I. D. R.). The range finders observe the battlefield, estimate the range to any targets appearing in view, without being specifically told to do so, communicate the range found to the platoon commander (this should not be done by shouting, as misunderstandings might result therefrom), and observe the effect of the fire. (Par. 173 German I. D. R.).
Whenever the flanks of a skirmish line are not protected by other troops or by natural obstacles, a few men under a prudent leader should always be sent out as combat patrols to the flank, or better still, to the right or left front. The patrol should under no circumstances lose connection with the command which it is to protect, but, on the other hand, should not stick so close to it that the file on the exposed flank is in a position to see as much as the combat patrol itself. As a report from a combat patrol frequently arrives too late, or cannot be made at all on account of hostile fire, signals should be agreed upon and the leader of the squad on the exposed flank of the line should keep the combat patrol constantly in view. Signal flags may also be employed advantageously in such cases.
The Austrian deployment is similar to the German, the intervals between
skirmishers being about two paces. In Italy the skirmishers are
posted at intervals of 1.5 m. (catena ordinaria), but this interval may be
increased by order up to three paces (catena rada). The interval between
squads in extended order is 4-5 paces to facilitate volley fire by squad.
The French deployment is similar to the German. An intermediate
extended order formation is that in which an advance is made in line, the
files at extended intervals. In England skirmishers are placed at intervals
of 5-15 paces during the initial deployment. At short ranges where the
decision is sought, one rifle per 2-3 yards of front (1.8-2.7 m.) is the
rule, one rifle per yard of front (0.90 m.) being the maximum. In Russia
and Japan the intervals are as ordered. In Switzerland skirmishers are
posted at intervals of 1-2 paces; when a greater front is to be covered the
intervals between squads are increased. The length of the rushes depends
on the ground, the effect of fire, and the endurance of the men. In exceptional
cases an advance by rushes, by squads or single men, is authorized.
