They should march in the rear of the battery when on a road, and on the outer flank when in open country and away from cavalry. The sole object of the machine guns is to afford protection to the battery from cavalry, and to prevent rifle fire from being brought to bear on them from effective range; therefore the section commander must devote his whole attention to this object, and he is not justified in opening fire on any target that does not directly threaten the battery--this especially applies to that stage of the mounted combat immediately before the collision, when the guns are firing on the opposing squadrons. The section commander will be under the immediate orders of the battery commander, and should be acquainted with his plans and intentions. He should remain with him until the position for action has been selected, when he will immediately seek the best position from which to cover the guns, taking particular care not to mask or limit their radius of fire nor hinder their line of advance or retreat. This will necessitate a careful but rapid survey of the ground in the vicinity of the position, in which good ground scouts, who have been previously trained in this work, will materially assist. The most suitable positions will usually be found well to the front and on the inner flank of the battery from 200 to 600 yards’ distance. It may be occasionally possible to place a machine gun on each flank from which a cross fire can be brought to bear on ground in front of the guns; but such a position on either side of the battery, unless the ground is particularly favourable, has the disadvantage of rendering fire control difficult, and may hamper the fire or movement of the battery. The principal considerations which should govern the choice of a position are as follows: (1) Good field of fire to protect the battery from attack. (2) Position clear of the fire and movement of the battery. (3) Immunity from artillery firing on the battery. (4) Concealment. (5) Cover from fire.
