=9. Resting Arm or Rifle.=--A coat or waterproof-sheet may be used to protect the uniform, but _except when firing from cover, or when rests are authorized, neither rifle, forearm, wrist, nor hand, is to rest against anything, or to be supported_. =10.= No one is allowed at the firing-point, except the men actually firing, the instructors, and officers. All non-commissioned officers and men not on duty at the firing-point will ground or pile arms, and remain not less than 30 yards in rear of the firing-point. No shouting is allowed; men next to fire will be brought up by signal. =11. Instruction during Intervals of Firing.=--(i) During intervals of firing an opportunity should be given occasionally to all ranks for revising their impressions as to the visibility of the human figure at short distances, by placing men on the firing-platforms up the range. The study of visibility under conditions of known distance and in relation to targets used for practice in shooting is especially valuable. (ii) Those men who are not actually engaged in firing should receive instruction in ground reconnaissance, use of the eyes, use of field-glasses, range-finding, and description of ground, while waiting behind the firing-point. =12. Field-Glasses.=--Field-glasses or telescopes will be carried by all officers and section commanders. The men should be encouraged to use them during spare time on the range. =13. Condition of Sights.=--The sights will be used as issued, without alteration of any kind. They may not be blackened; the browning is renewed by an armourer when required. No additions, marking, or colouring, are permitted, nor are orthoptics allowed. =14. Observation Practices.=--The change which takes place in conditions of shooting when there is no signalling of each shot is not always appreciated, and it is essential that the importance of the first application of fire should be realized. Troops, therefore, which are unable to fire field practices should fire some at least of the instructional practices without signalling. Such practices are called “observation practices.” The targets should be placed on the face of the stop-butt or at the foot of the gallery-bank, and may with advantage be falling or collapsible targets. =15. Precautions.=--To guard against accidents, the following orders will be observed: (i) No firing will take place until a large red danger-flag is hoisted on the signal-staff at or near the butts, and the necessary look-out men posted. (ii) A smaller red danger-flag will be hoisted at the butts as a warning to cease fire. This flag will remain exposed during the entire period of cessation of fire, and will not be withdrawn until the whole of the butt party is under cover. No one will leave the butts until cessation of fire has been notified from the firing-point.
