Persons who enlist in the Navy Reserve's Active Duty program first sign a contract to enter the Ready Reserve for a period of time that coincides with time served on Active Duty. Upon separation from Active Duty, members may still be obligated by their Reserve contract if it has not expired. The remainder of the contract may be served as a member of the Selected Reserve or the Individual Ready Reserve.ADMINISTRATIVE PROCEDURES FOR NAVY RESERVISTS BUPERSINST 1001.39F
