The regulations consider the involuntary defense in a rencontre; the deliberately prepared defense seeking a decision and contemplating an assumption of the offensive; the defense for the purpose of gaining time; and the occupation of a position in readiness, when the direction in which the hostile attack will be made is still in doubt, or when the commander intends to assail the enemy while the latter is in the act of deploying. In the defense seeking a decision, advanced positions are not to be used, because it is believed that the employment of detachments of troops in front of the defensive position will weaken the latter, and a hostile enveloping attack will soon force the advanced troops to fall back upon the main position. The regulations point out that if the advanced troops are supported by fire from the main position, the latter will be prematurely disclosed to the assailant. The employment of advanced troops is, however, considered justifiable to hold defiles, to deceive the enemy, or to support the cavalry.
The works of a position are not to be continuous, but are to be constructed in groups. Infantry positions over which artillery is to fire are not to be less than 500 m. in front of the latter.
