For example, following the same order as before, the mobility of this type of guerrilla should be extraordinary; strikes should be made preferably at night; they should be extremely rapid, but the guerrilla should move to places different from the starting point, the farthest possible from the scene of action, assuming that there is no place secure from the repressive forces that the guerrilla can use as its garrison.
A man can walk between 30 and 50 kilometers during the night hours; it is possible also to march during the first hours of daylight, unless the zones of operation are closely watched or there is danger that people in the vicinity, seeing the passing troops, will notify the pursuing army of the location of the guerrilla band and its route. It is always preferable in these cases to operate at night with the greatest possible silence both before and after the action; the first hours of night are best. Here, too, there are exceptions to the general rule, since at times the dawn hours will be preferable. It is never wise to habituate the enemy to a certain form of warfare; it is necessary to vary constantly the places, the hours, and the forms of operation.
We have already said that the action cannot endure for long, but must be rapid; it must be of a high degree of effectiveness, last a few minutes, and be followed by an immediate withdrawal. The arms employed here will not be the same as in the case of actions on favorable ground; a large quantity of automatic weapons is to be preferred. In night attacks, marksmanship is not the determining factor, but rather concentration of fire; the more automatic arms firing at short distance, the more possibilities there are of annihilating the enemy.
Also, the use of mines in roads and the destruction of bridges are tactics of great importance. Attacks by the guerrilla will be less aggressive so far as the persistence and continuation are concerned, but they can be very violent, and they can utilize different arms, such as mines and the shotgun. Against open vehicles heavily loaded with men, which is the usual method of transporting troops, and even against closed vehicles that do not have special defenses-against buses, for example-the shotgun is a tremendous weapon. A shotgun loaded with large shot is the most effective. This is not a secret of guerrilla fighters; it is used also in big wars. The Americans used shotgun platoons armed with high-quality weapons and bayonets for assaulting machine-gun nests.
There is an important problem to explain, that of ammunition; this will almost always be taken from the enemy. It is therefore necessary to strike blows where there will be the absolute assurance of restoring the ammunition expended, unless there are large reserves in secure places. In other words, an annihilating attack against a group of men is not to be undertaken at the risk of expending all the ammunition without being able to replace it. Always in guerrilla tactics it is necessary to keep in mind the grave problem of procuring the war materiel necessary for continuing the fight.
