This is from Norwich's website:
Participation in ROTC, including military labs and physical training, is an integral part of the Corps leadership experience at Norwich. Cadets must enroll in Army, Air Force, Navy or Marine Corps ROTC to maintain membership in the Corps of Cadets, and complete six semesters of ROTC courses; two apiece at the 100, 200, and 300 levels. All ROTC participants, with the exception of nursing students, must be in the Corps.
Students transferring into the Corps of Cadets are required to pass a course in ROTC for each semester in the Corps.
The ROTC requirement is both an obligation and an extraordinary opportunity. Cadets will study leadership, ethics, troop-leading skills and a broad array of military service-related courses.
Cadets who participate in six semesters of ROTC are under no obligation to serve in the Armed Services. Those who wish to pursue a career as a commissioned officer compete for that opportunity by earning an ROTC scholarship or placement on a commissioning track.
