This document provides an overview and instructions for military drill. It summarizes key aspects of drill, including purposes of drill, instruction methods, types of commands, and proper voice techniques for delivering commands. Drill is used to move units in an orderly manner, provide simple formations, teach discipline, and increase confidence. Good drill instructors must follow regulations strictly, have energy and patience, and demonstrate neatness and bearing while closely observing and correcting trainees. There are four types of commands - preparatory, execution, combined, and supplementary. Proper inflection and emphasis are required to project commands and inspire precise responses from personnel.
