Owing to shortage of good drill masters groups for this preliminary work will have to be larger than is customary in peace time in the regular service, not less than eight men to a group from the start, and these should be combined into groups of two squads each then into platoons, as soon as their work permits. The best instructors should be kept as drill masters after each consolidation. For the callisthenic drills from the very start the men can be combined into large groups and instructors found who are already competent to drill their squads in the school of the soldier. The other squad commanders who are imperfectly prepared must be assembled at this time for drill and instruction under the best officers and non-commissioned officers in the regiment. They will be carefully taught the next movements to be given to the men and how to teach them to their squads. As these squad leaders are selected as far as possible from those having had some military training and the others from the brightest and most intelligent men, it is believed possible for them to keep ahead of their squads. It becomes easier as the groups grow larger and fewer instructors are required. The drill will be given to the officers who do not know it. The officers being formed into a squad by themselves. All trained officers must be on the drill ground during all these drills by squad, supervise the work, correct mistakes and help out the poorer instructors. The other officers not acting as instructors should be required to attend about half to learn from seeing it done, the other half of this time they should be required to be drilled themselves and to study the drill regulations. There should be no hesitation in having lieutenants drill squads during this period provided they are better at it than some of the enlisted men and are not needed to supervise the work of several squads. [Sidenote: Officers’ school] There should be an officers’ school every evening except Saturdays and Sundays. This should be conducted by the colonel himself. The first subject taken up being the drill regulations. Lessons should be short as well as the sessions of the class and the work thoroughly done. The student officer must learn the text and the instructor fully explain it where necessary. Much explanation will be required in Part II. The class must keep well ahead of the outdoor work. Besides the Infantry Drill Regulations, in this school must be taught early in the course, parts of the Guard Manual and Small Arms Firing Manual. The essential parts of the Field Engineering will be taught, and, those not proficient therein, how to read military maps. Lastly take up the Manual of Courts Martial.
