When you entered the service, you incurred a military service obligation of eight years. If you are separating prior to fulfilling eight years of service, then some of that obligation probably remains even though you are returning to civilian life. You must satisfy that obligation by becoming a member of the Ready Reserve in one of the following categories:
- Selected Reserve: You may voluntarily affiliate with the Selected Reserve, either with a National Guard or Reserve unit, or a Reserve individual program.
- Inactive National Guard: If you served in the Army, you may become a member of the Army National Guard and request transfer to the Inactive National Guard if unable to participate in regular unit training.
- Individual Ready Reserve (IRR): If you do not affiliate with one of the above programs, your service will automatically or involuntarily assign you to the Individual Ready Reserve.
