Knew a HT3 who got out after a four-year hitch. One of the other sailors in his division sad that the guy would re-enlist before the expiration of his eligibility to come back in. When I asked why, he said: "Because in CivLant, they don't let you get away with sleeping in fan rooms."
He was right, the HT3 re-upped five days before the end of the eligibility period.
