The advantages of obtaining instructor's certificate for college students in future job hunting are: if you plan to get a job directly, it is more advantageous to have more certificates, but it is best to have certificates related to your industry or in some languages. What I said may only apply to liberal arts majors, but science and engineering are not clear. Instructor's certificate can well prove that you can really undertake the post of military training instructor, and you can take this as a career to be an instructor on major campuses. If your own ability is excellent, you will be invited by major universities. If you are a student, you can add credits if you have a military training instructor's certificate, and you can also help the teacher train the next schoolmate.
