and the suddenness of its appearance. The soldier judges the magnitude of danger by the number of hostile projectiles and by their effect. Therefore, the livelier the hostile fire, and the longer it continues, the greater the danger appears to him; while the less the effect of that fire, and the better he is sheltered from it, the less he will think himself endangered. On this account, the nervous tension of the individual soldier will reach different degrees of intensity according to the magnitude of the danger.
"Now there are combat situations where the danger is insignificant, and entire engagements in which the impression produced by danger may be called moderate; moreover, even in lively actions phases may occur in which this is equally true. The circumstances of each particular case will, therefore, determine how long it is possible to fire as prescribed in the firing regulations, and from what moment a reduction of efficacy, according to Colonel Wolozkoi's theory, is unavoidable.
"The arrival of this moment will be postponed more or less by better discipline and training; and, in addition, at the commencement of an action, we may count on the men putting into practice, to a certain extent, what they have been taught in time of peace. However, the efficacy of rifle fire will deteriorate gradually, as the danger and the intensity of the fight increase, until it reaches the stage which Wolozkoi considers peculiar to all of the more serious actions.
