In 1969, Hubbard replaced the Mud Box Brigade with the Rehabilitation Unit, again intended for those removed or disciplined "as ineffective or trouble." Following an evaluation, the individual was to receive a set of "specific recommendations which if followed will rehabilitate the individual as a highly effective and worthwhile Sea Org member." Hubbard instructed that "(T)he unit is be worked hard during the day on a rigorous schedule on jobs assigned by the Review Chief handling corrective areas and jobs needing remedy and repair. The Unit itself is thus made into an effective ship's review team. It works on a one job, one time, one place formula completing each job before moving into the next. Each individual thus earns the right to the remedial services he or she will receive."
