A sailor re-enlists for 4 years on 02NOV17. When is their EAOS?

To determine the Enlisted Active Obligation Service (EAOS) for a sailor who re-enlists for four years, we start by recognizing that the end of the enlistment period is calculated from the date of re-enlistment. In this case, the sailor re-enlisted on November 2, 2017.

Therefore, rather than leaving it on the 2nd, the EAOS would actually end on the first day of the following month, which would be December 1, 2021.

Thus, the EAOS is established as November 1, 2021, making the sailor eligible to complete their service by that date. As a result, the correct answer reflects this adjustment because it is understood that some reference materials or docs might present EAOS as December 1, 2021, marking the beginning of a new month.
