Leadership Laboratory (LLAB) is a weekly 1-2 hour pass/fail class that trains and prepares cadets for Field Training (FT), develops leadership skills, and promotes Espirit de Corps among all cadets. At some universities, credit hours may be given for completing LLAB. For GMC cadets, LLAB provides new cadets with basic skills and knowledge to be a functional member of the cadet corps, prepares them in Warrior Knowledge and Drill and Ceremonies (marching), and teaches leadership, followership, and teamwork skills. For POC cadets, LLAB furthers leadership and followership skills learned at FT by planning and implementing the activities under the supervision of the active-duty cadre.

Specific LLAB activities are determined by the detachments themselves and thus vary across the nation. Some specific activities include: Field trips to Air Force bases and stations (to include Air Force Reserve and Air National Guard installations), Field Days, physical fitness tests and competitions, Drill and Ceremonies, leadership-building exercises, and Air Force officer career days.
