flanks are especially vulnerable to modern firearms. The moral effect of flanking fire is as great as the physical effect. Hence, combat patrols to give warning or covering detachments to give security are indispensable on exposed flanks. This is equally true in attack or defense. (396)

411. Responsibility of infantry commanders for reconnaissance; surprise unpardonable. The fact that cavalry patrols are known to be posted in a certain direction does not relieve infantry commanders of the responsibility for reconnaissance and security.

To be surprised by an enemy at short range is an unpardonable offense. (397)

412. Commander of flank battalion responsible for security of his flank. The commander of a battalion on a flank of a general line invariably provides for the necessary reconnaissance and security on that flank unless higher authority has specifically ordered it. In any event, he sends out combat patrols as needed.

Where his battalion is on a flank of one section of the line and a considerable interval lies between his battalion and the next section, he makes similar provision. (398)

413. Patrols established by battalion commanders. Battalion commanders in the first line establish patrols to observe and report the progress or conduct of adjoining troops when these can not be seen. (399)

FIRE SUPERIORITY

PURPOSE AND NATURE

(See par. 427)

414. Success in battle dependent upon fire superiority. In a decisive battle success depends on gaining and maintaining fire superiority. Every effort must be made to gain it early and then to keep it.

Attacking troops must first gain fire superiority in order to reach the hostile position. Over open ground attack is possible only when the attacking force has a decided fire superiority. With such superiority the attack is not only possible, but success is probable and without ruinous losses.

Defending troops can prevent a charge only when they can master the enemy's fire and inflict heavy losses upon him. (400)

415. Volume and accuracy necessary to obtain fire superiority. To obtain fire superiority it is necessary to produce a heavy volume of accurate fire. Every increase in the effectiveness of the fire means a corresponding decrease in the effectiveness of the enemy's fire.

The volume and accuracy of fire will depend upon several considerations:

(a) The number of rifles employed. On a given front the greatest volume of fire is produced by a firing line having only sufficient intervals between men to permit the free use of their rifles. The maximum density of a firing line is therefore about one man per yard of front.

(b) The rate of fire affects its volume; an excessive rate reduces its accuracy.

(c) The character of the target influences both volume and accuracy. Larger dimensions, greater visibility, and shorter range increase the rate of fire; greater density increases the effect.

(d) Training and discipline have an important bearing on the rate or volume of fire, but their greatest influence is upon accuracy.

The firing efficiency of troops is reduced by fatigue and adverse psychological influences.

(e) Fire direction and control improve collective accuracy. The importance of fire direction increases rapidly with the range. Control exerts a powerful influence at all ranges. (401)

FIRE DIRECTION AND CONTROL Opening Fire

416. Long range fire, when effective. Beyond effective ranges important results can be expected only when the target is large and distinct and much ammunition is used.

Long range fire is permissible in pursuit on account of the moral effect of any fire under the circumstances. At other times such fire is of doubtful value. (402)

417. Opening fire in attack. In attack, the desire to open fire when losses are first felt must be repressed. Considerations of time, target, ammunition, and morale make it imperative that the attack withhold its fire and press forward to a first firing position close to the enemy. The attacker's target will be smaller and fainter than the one he presents to the enemy. (403)

418. Opening fire in defense. In defense, more ammunition is available, ranges are more easily determined, and the enemy usually presents a larger target. The defender may therefore open fire and expect results at longer ranges than the attacker, and particularly if the defenders intend a delaying action only.

If the enemy has a powerful artillery, it will often be best for the defending infantry to withhold its fire until the enemy offers a specially favorable target. Vigorous and well-directed bursts of fire are then employed. The troops should therefore be given as much artificial protection as time and means permit, and at an agreed signal expose themselves as much as necessary and open fire. (404)

419. Opening fire in unexpected, close encounters. In unexpected, close encounters a great advantage accrues to the side which first opens rapid and accurate fire with battle sight. (405)

Use of Ground

420. Requisites of ground for cover. The position of the firers must afford a suitable field of fire.

The ground should permit constant observation of the enemy, and yet enable the men to secure some cover when not actually firing.

Troops whose target is for the moment hidden by unfavorable ground, either move forward to better ground or seek to execute cross fire on another target. (406)

421. Skillful use of ground reduces visibility. The likelihood of a target being hit depends to a great extent upon its visibility. By skillful use of ground, a firing line may reduce its visibility without loss of fire power. Sky lines are particularly to be avoided. (407)

Choice of Target

422. Target to be chosen. The target chosen should be the hostile troops most dangerous to the firers. These will usually be the nearest hostile infantry. When no target is specially dangerous, that one should be chosen which promises the most hits. (408)

423. Target not to be changed except for good reason. Frequent changes of target impair the fire effect. Random changes to small, unimportant targets impair fire discipline and accomplish nothing. Attention should be confined to the main target until substantial reason for change is apparent. (409)

424. Flanking fire to be delivered when opportunity offers. An opportunity to deliver flanking fire, especially against artillery protected in front by shields, is an example warranting change of target and should never be overlooked. Such fire demoralizes the troops subjected to it, even if the losses inflicted are small. In this manner a relatively small number of rifles can produce important results. (410)

The Range

425. Importance of correct sight setting. Beyond close range, the correct setting of the rear sight is of primary importance, provided the troops are trained and well in hand. The necessity for correct sight setting increases rapidly with the range. Its importance decreases as the quality of the troops decrease, for the error in sight setting, except possibly at very long ranges, becomes unimportant when compared with the error in holding and aiming. (411)

426. Determination of ranges. In attack, distances must usually be estimated and corrections made as errors are observed. Mechanical range finders and ranging volleys are practicable at times.

In defense, it is generally practicable to measure more accurately the distances to visible objects and to keep a record of them for future use. (412)

Distribution of Fire and Target

427. Purpose of fire superiority; distribution of fire and target. The purpose of fire superiority is to get hits whenever possible, but at all events to keep down the enemy's fire and render it harmless. To accomplish this the target must be covered with fire throughout its whole extent. Troops who are not fired upon will fire with nearly peacetime accuracy.

The target is roughly divided and a part is assigned to each unit. No part of the target is neglected. In attack, by a system of overlapping in assigning targets to platoons, the entire hostile line can be kept under fire even during a rush. (Pars. 400–401.) (413)

Observation

428. Observation of target. The correctness of the sight setting and the distribution of fire over the target can be verified only by careful observation of the target, the adjacent ground, and the effect upon the enemy. (414)

429. Observation determines whether fire fight is being properly conducted. Observation only can determine whether the fire fight is being properly conducted. If the enemy's fire is losing in accuracy and effect, the observer realizes that his side is gaining superiority. If the enemy's fire remains or becomes effective and persistent, he realizes that corrective measures are necessary to increase either volume or accuracy, or both. (415)

Discipline

430. What discipline accomplishes. Discipline makes good direction and control possible and is the distinguishing mark of trained troops. (416)

431. Communication on firing line by means of signals. The discipline necessary in the firing line will be absent unless officers and noncommissioned officers can make their will known to the men. In the company, therefore, communication must be by simple signals which, in the roar of musketry, will attract the attention and convey the correct meaning. (417)

Expenditure of Ammunition

432. Use of ammunition in attack. In attack the supply is more limited than in defense. Better judgment must be exercised in expenditure. Ordinarily, troops in the firing line of an attack can not expect to have that day more ammunition than they carry into the combat, except such additions as come from the distribution of ammunition of dead and wounded and the surplus brought by reënforcements. (418)

433. True economy in expenditure of ammunition. When a certain fire effect is required, the necessary ammunition must be expended without hesitation. Several hours of firing may be necessary to gain fire superiority. True economy can be practiced only by closing on the enemy, as explained in par. 344, before first opening fire, and thereafter suspending fire when there is nothing to shoot at. (419)

Supporting Artillery

434. Artillery fire principal aid of infantry. Artillery fire is the principal aid to the infantry in gaining and keeping fire superiority, not only by its hits, but by the moral effect it produces on the enemy. (420)

435. Functions of artillery fire in attack and defense. In attack, artillery assists the forward movement of the infantry. It keeps down the fire of the hostile artillery and seeks to neutralize the hostile infantry by inflicting losses upon it, destroying its morale, driving it to cover, and preventing it from using its weapons effectively.

In defense, it ignores the hostile artillery when the enemy's attack reaches a decisive stage and assists in checking the attack, joining its fire power to that of the defending infantry. (421)

436. Fire of artillery over friendly troops. Troops should be accustomed to being fired over by friendly artillery and impressed with the fact that the artillery should continue firing upon the enemy until the last possible moment. The few casualties resulting from shrapnel bursting short are trifling compared with those that would result from the increased effectiveness of the enemy's infantry fire were the friendly artillery to cease firing.

Casualties inflicted by supporting artillery are not probable until the opposing infantry lines are less than 200 yards apart. (422)

437. When no longer safe for artillery to fire over friendly troops. When the distance between the hostile infantry lines becomes so short as to render further use of friendly artillery inadvisable, the commander of the infantry firing line, using a preconcerted signal,[5] informs the artillery commander. The latter usually increases the range in order to impede the strengthening of the enemy's foremost line, as explained in pars. 345–346. (423)

Fire of Position

438. Fire of position, when used. Infantry is said to execute fire of position when it is posted so as to assist an attack by firing over the heads, or off the flank, of the attacking troops and is not itself to engage in the advance; or when, in defense, it is similarly posted to augment the fire of the main firing line.

Machine guns serve a like purpose, as
