I am a Combat Instructor. I am a mentor and leader to my students. I am the example of a combat ready Marine, and will inspire my students to emulate me. I will mentally and physically train them in infantry tactics, techniques and procedures. I will train them with vigor, enthusiasm, and make them combat efficient. I will treat them with firmness, fairness, dignity and respect. My moral courage, leadership and discipline are unquestionable and my students will never fear me. I will never forget I am accountable to my Marines to provide them the training necessary to survive in combat.
