=4. Anticipatory Orders.=--Fire orders should anticipate events as far as possible, so that lengthy orders will not be needed after the target appears. The following is an example of an anticipatory order, which includes the use of combined sights: _The enemy is about to advance from that fir-wood on the hill half left. When he moves, concentrate on the thickest part of his line--1250 and 1350._ =5.= If all ranks are kept informed of the course of events,[24] and led to anticipate occasions for fire action, _there should be no need for any words of command other than those which regulate movement, the opening and closing of fire, and the rate of fire_; and even these may be dispensed with if the firers are well trained, and combine their efforts according to orders issued in anticipation. _The results of observation and alterations to be made in sighting or point of aim must be notified at once._ =6. Instruction in Fire Orders.=--Fire-unit commanders, observers, and N.C.O.’s should be thoroughly trained in giving clear, concise fire orders under practical conditions. They must watch to see if their orders are understood by the actions of their men. _Men must be trained not to put their rifles to their shoulders until they understand the orders given and recognize the target indicated._ This rule is essential _to prevent useless waste of ammunition in war_, and to serve as a check in peace training, as to whether orders are given or passed from man to man so that they are immediately understood and carried out by the men. It will enable fire-unit commanders to know when their orders are not heard or understood, and also enable company and platoon commanders to supervise the training of fire-unit commanders. =7. Passing Fire Orders from Man to Man.=--(i) Soldiers are trained in passing short verbal messages and orders accurately and quickly as part of their field-training, and this instruction is contained in _Drill and Field-Training_ of this series in Sec. 8 and also in Sec. 42, which deals with training in passing messages in whispers during night operations. Training in passing fire orders quickly and accurately from man to man is a vitally important part of the musketry training of N.C.O.’s, observers, and men. Orders passed from man to man in the firing-line must be short. They may be passed a sentence or two at a time, or as a whole, the latter being the best and quickest method if orders are short.
