What is an RE-4 discharge?

An RE-4 discharge is a type of reentry code used by the U.S. military to indicate that a service member is ineligible for re-enlistment. This code is typically assigned for reasons such as misconduct, failure to meet performance standards, or other disciplinary issues. While it does not specify the exact reason for ineligibility, it generally suggests that the individual may face challenges in pursuing a military career in the future.
