<P> To reinforce the importance of honor, character and integrity to future officers, cadets are given an extensive character and leadership curriculum . The Academy's Center for Character and Leadership Development provides classroom, seminar, workshop and experiential - based learning programs to all cadets, beginning when they enter Basic Cadet Training and continuing each year through their last semester at the Academy . The Center's programs, when coupled with the Honor Code and Honor System, establish a foundation for the "leaders of character" that the Academy aspires to produce . </P> <P> The Academy's organization is unusual in a number of respects . Because it is primarily a military unit, much of the Academy's structure is set up like that of any other Air Force Base . This is particularly true of the non-cadet units--most assigned to the 10th Air Base Wing--that provide base services such as security, communications, and engineering . Because the Academy is also a university, however, the organization of the faculty and the Cadet Wing have some aspects that are more similar to the faculty and student body at a civilian college . </P> <P> The student body of the Academy is known as the Cadet Wing . The students, called "cadets", are divided into four classes, based on their year in school, much like a civilian college . They are not referred to as freshmen, sophomores, juniors and seniors, however, but as fourth -, third -, second - and first class cadets, respectively . Fourth class cadets (freshmen) are often referred to as "doolies," a term derived from the Greek word δοῦλος ("doulos") meaning "slave" or "servant ." Members of the three lower classes are also referred to as "4 degrees," "3 degrees" or "2 degrees" based on their class . First - class cadets (seniors) are referred to as "firsties ." In the military structure of the Cadet Wing, first class cadets hold the positions of cadet officers, second class cadets act as the cadet non-commissioned officers and third class cadets represent the cadet junior non-commissioned officers . </P> <P> The Cadet Wing is divided into four groups, of ten cadet squadrons each . Each cadet squadron consists of about 110 cadets, roughly evenly distributed among the four classes . Selected first -, second - and third - class cadets hold leadership, operational and support jobs at the squadron, group and wing levels . Cadets live, march and eat meals with members of their squadrons . Military training and intramural athletics are conducted by squadron as well . Each cadet squadron and cadet group is supervised by a specially selected active duty officer called an Air Officer Commanding (AOC). In the case of a cadet squadron, the AOC is normally an active duty Air Force major . For a cadet group, the AOC is normally an active - duty lieutenant colonel . These officers have command authority over the cadets, counsel cadets on leadership and military career issues, oversee military training and serve as role models for the future officers . In addition to an AOC, cadet squadrons and groups are also supervised by an active duty non-commissioned officer known as an Academy Military Trainer (AMT), who fulfills a similar job as the AOC . </P>
