Each of the NSCC and NLCC's 396 units perform drills all around the United States during the school year. Some units have a weeknight drill of 2–3 hours, or drill for an entire day over the weekend twice a month, while others drill once a month for an "entire" weekend. Each unit's drill schedule is set by the unit Commanding Officer and depends on the location of the unit and availability of both adult staff and cadets. During the school year, nearby units often come together to participate in weekend trainings, including Field Training Exercises, Small Arms Training, Shipboard Training, and Regional Flagship Competitions.
