_Para. 218._--From the very beginning of an action it must be remembered that the number of cartridges carried is limited, and that the consumption of ammunition implies an expenditure of power which should only be made when it will meet with success. Should the decision be taken, however, to fire on a given target, the ammunition necessary to attain the object of the action must be expended. Fire with an insufficient effect weakens the morale of the troops, whilst it encourages the enemy. _Para. 219._--The losses inflicted on the enemy will affect him more if he incurs them in a short space of time, than if they are distributed over a long period; it is advisable therefore in most cases, even in the face of a weaker enemy, to open fire with the whole detachment rather than with one or two sections only. The expenditure of ammunition necessary for the silencing of the enemy will in both cases be about the same, but in the former case one’s own loss will be appreciably smaller. _Para. 220._--A change of objective should not be made until the result aimed at against the first target has been fully realised. A frequent change of objective weakens the fire, and should therefore be avoided. _Para. 221._--A distribution of fire over several objectives cannot be avoided under all circumstances, but it must not resolve itself into an aimless scattering of fire. _Para. 222._--In every case coolness, marksmanship, and strict fire discipline are necessary to get full value in fire effect. In an engagement, should the majority of those in command be put out of action, fire discipline must still be preserved. With well-trained and well-disciplined troops, the presence of mind of the individual soldier, and the example of stout-hearted and cool-headed men will ensure a successful conclusion to an engagement fought against an enemy in a similar plight. _Para. 223._--The officer commanding the troops announces the object of the action, and also the objective in a general way. _Para. 224._--The machine-gun detachment commander selects the positions, determines the range, names the targets in detail together with the nature of attack on them, and orders the opening of fire. _Para. 225._--The section commander passes on the orders. He decides the place for each gun, also the portion of the objective to be fired at, and the range for each individual weapon. He observes the service of the guns, and is especially responsible that the correct target is fired at and for the fire action of his section. _Para. 226._--The No. 1 of the gun selects the spot to place his gun, and the most suitable height for it to stand above ground, follows in detail all orders, and ensures (using in case of necessity independent measures) that the centre of the cone of dispersion falls on the target. He is responsible for the service of the gun in detail, and attentively watches the weapon so as to remedy any defects which might interfere with its fire effect.
