You're in college to get an education, enter a well-respected profession and earn a good living. Decisions about going into the Air Force, and a possible career, don't come overnight. Your choice of study is one decision that could affect the specialties available to you in the Air Force.
Some fields of study are more closely related to some specialties than others.
For example, the obvious officer specialty for a criminal justice major would be Security Forces or Special Investigations. It is important that you understand that what you are majoring in now will have a tremendous impact on what career you enter initially in the Air Force. However, this does not mean that a history major cannot become a pilot or navigator. There are pilots in the Air Force right now who were general studies and finance majors. This also doesn't mean that a particular major guarantees a certain active duty job.
