Correct. That is what Overpaid Union Thug said and I agreed with. Less than 5 years and UPS has to hold your job. Longer than that is a career move.
Exceptions to the 5-year limit can be grouped into three broad categories:
Unable (through no fault of the individual) to obtain release from service or service in excess of five years to fulfill an initial period of obligated service (generally imposed on Active component aviators or others who undergo extensive initial training in certain technical military specialties).
Required drills and annual training and other training duty certified by the military to be necessary for professional development or skill training/retraining.
Service performed during time of war or national emergency or for other critical missions/contingencies/military requirements. Involuntary service of this type is exempt from the 5-year limit. Voluntary service in support of the mission/contingency/military requirement is also exempt. (Section 4312).
Wouldn't this cover a seal initial enlistment of 6 years? Or the fact that seals may have to receive specialized training for critical missions?
