Drill Instructor



A drill instructor (DI) is a non-commissioned officer in the armed forces assigned the duty of indoctrinating new recruits entering the military into the customs and practices of military life. The title varies depending upon the branch. The Marines refer to a DI as "Sergeant Instructor" at Officer Candidate School and Drill Instructor for enlisted boot-camp. The Fleet refers to them as "Recruit Company Commanders" and only uses them at enlisted boot-camp. The tour of duty is three years and is widely regarded as one of the most intense, demanding, and important duties in the Union Armed Forces. It can often be one of the most important duties of a military career because the responsibility is most directly involved with creating the future personnel of the armed forces.

The Drill Instructor Creed of the United Stars Marine Corps is:
 * "These recruits are entrusted to my care.
 * I will train them to the best of my ability.
 * I will develop them into smartly disciplined, physically fit, basically trained Marines, thoroughly indoctrinated in love of Corps and country.
 * I will demand of them, and demonstrate by my own example, the highest standards of personal conduct, morality and professional skill."
