This reference work was originally published by the French General Staff under the title Manual of the Chief of Platoon of Infantry. This is a manual of instruction for platoon commanders and NCOs regarded as potential commanders. It was to be used as the basis of training given in units at rest, in Schools of Instruction in the Armies and was also intended for officer-instructors at depots and camps of instruction in the interior. It was to be a guide for the new arrivals so that they might be quickly ready to conduct themselves and fight like their comrades in the line. Every aspect of trench warfare is considered - tactics, organization, weapons, equipment, communications etc. A number of chapters are shown in the contents as "Omitted" - presumably on security grounds.
