There are several retirement plans available for military veterans, but their availability is often dictated by the length of the veteran’s career and when they entered the service. The military currently has five different retirement plans active, most of them defined by when the individual began their tenure in the military. The plans are Final Pay, High-36, CSB/REDUX, Blended Retirement System, and Disability. The Disability plan is the only one that does not rely on their entry date but rather on if the veteran was deemed medically unfit for service.
