Things that people don't think about when re-enlisting....
2 years in.....STAR reenlist (which, in the most recent Navy Times, ET rates are in critical need of people, SO...the cap has gone up to 90-100K (not sure exactly) for zone A (first time enlistment)...you might want to find that Navy Times because I'm not sure if it was all ET's or just Sub ET's (depends on your NEC).
Taking you to 8 years in.....which depending on the needs of the Navy, luck or your ability to get a good deal around the 5 1/2 to 6 1/2 year point you will probably be considering SHORE DUTY, but in order to accomplish this you will have to re-enlist again (or extend...with no bonus), putting you up to the 10 year point.
SO think about that....if you re-enlist now, there is a good possibility you will face that decision again, but with a Shore Duty to deal with (much easier to talk yourself into than staying at SEA)
You are now getting to your 10 year point (which is where I will be) and you find this site, and wish you had found this site 3 years ago!......oh sorry, got off topic......This is where you reach a critical point--
--If you re-enlist now, you might as well settle in for 20 years. (Listening to Master Chief's discuss their retirement pay is nice, but if you listen closely you realize that they will still need to get another job to supplement that pay (unless they have made sound financial decisions).
--Or you realize that the civilian world is the place to be.
Don't get me wrong, I don't regret joining the Navy or staying in as long as I have....I have been able to finish my degree and gained experience being an Instructor and SLPO, which I believe will better help my transition out of the Navy.
My best recommendation to the decision of re-enlisting: Get some more information from honest, unbiased opinions (as difficult as it may be), and see the BIG picture!! (subsequent decisions to re-enlist and the decision to go career or not)
Good luck with your decision!
