Prior Service Enlistment Bonuses are available to military personnel who have been separated from the military for more than 90 days, and who possess a critical military skill.
While re-enlistment bonus amounts are generally computed using "multipliers," based on the MOS and how many years one has been in the service, the Army has placed a "cap" on the maximum amounts authorized, based on how "critical" the MOS (job) is.
