What is one of the purposes of close order drill?

One of the primary purposes of close order drill is to instill discipline among service members. Through the repetitive actions and commands involved in close order drill, Marines learn to respond promptly and accurately, fostering a sense of obedience and respect for authority. This discipline is crucial for maintaining order in various situations, especially in combat scenarios where quick, coordinated movements can be vital to mission success. The structured environment of close order drill helps develop habits of precision, uniformity, and teamwork, which are essential values in a military setting, ultimately enhancing unit cohesion and effectiveness.

While the other options provide varying aspects of military training, they do not capture the primary focus of close order drill, which is fundamentally about developing disciplined service members who can operate effectively as part of a team.
