Which of the following is NOT a method used to teach drill?

The method of teaching drill known as "Individual practice" is not typically recognized as a standard instructional method for drill. In military training, drills are usually taught using structured methods that involve group participation and oversight by an instructor.

Step by step requires that the instructor break down movements into manageable segments for learners to understand and practice each part before linking them together, while "By the numbers" introduces drills through a systematic counting approach, ensuring precision and timing as they practice. The "Talk-through method" involves verbal instructions accompanying the actions, allowing for immediate understanding of movements.

Individual practice, although useful for reinforcement after introduction and group practice, does not serve as an instructional method in the initial stages of drill teaching, where group dynamics and immediate correction by instructors are essential for successful learning and discipline.
