Courtesy is indispensable to discipline and good order.
Exceptions to this are when a lesson, briefing, or examination is in progress. Cadets who are seated must stand when addressed by or addressing a commissioned officer except during AS class sessions.

See the appendix for rank insignia, titles and abbreviations.
