More intermediate strong points, built for all-round defence, were recommended between the first and second positions. Defence of the first position was still the intention but deeper defences would dissipate the effect of a breakthrough and force the attackers to make numerous individual attacks on ground where local knowledge and the preparation of defences would be advantageous to the defenders. Observation posts should be made secure from attack, reconnaissance reports acted on promptly and communication links were to be made as robust as possible.
More defensive positions, designed to be strong in all areas, were suggested between the first and second lines of defense. While the primary objective was still to defend the first line, deeper defenses would hinder a breakthrough and force attackers into numerous individual attacks on ground where local knowledge and preparation could give defenders an advantage. Observation posts needed to be secure from attack, reconnaissance reports had to be acted upon quickly, and communication links were to be made as reliable as possible.
