Were you a recruiter at one time in your life? Because the above post sounds an awful lot like the bullshit that recruiters would tell people to try to get them to go to MEPS.
Why do I say this? Because I was the person at the MEPS who had to undo all the bullshit notions put into their head by the recruiters who just wanted to get a contract. I was LPO and Head Classifier at Amarillo MEPS.
Does the Navy offer enlistment bonuses that sound too good to be true? Yes. They do. BUT..............you have to qualify for a program that is paying those big bonuses, as well as enlist specifically for that program (subject to availability of billets). The big bonuses for enlistment were mainly for the programs that it was very hard to get into (i.e. nuclear engineer), and to qualify for those programs it was a 2 tier process. First, you had to qualify for enlistment (ASVAB, physical and civil screenings), and then, if your initial enlistment qualifications made you look like you might qualify for the more advanced programs, they would do a second screening. For the nuclear program, if you had a high enough score on the ASVAB (over 75), then we would give you a nuclear test. IF you scored high enough on the nuke test, then we would see if there was a billet available and if so, enlist you for that program with all that sweet bonus.
HOWEVER....................the bonus comes with strings attached. First, you only get part of the money upon SUCCESSFUL completion of the nuclear school (and many people wash out due to not being able to handle the academics, and it's a 2 year training pipeline), then you get half of the bonus, with the other half being paid out in yearly increments for the rest of your 6 year enlistment.
Does the Navy have snipers? Yes. They are SEALs who successfully completed training for SEALs, and were further selected and trained to become snipers. VERY few will ever get to that point, because VERY few make it through the initial training.
Air Traffic Controller or something in electronics or communications? You bet. The Navy has all of those programs, but again, just like nuclear programs, your ASVAB score has to be high enough to qualify for the program, there has to be a billet, and you have to complete training for it.
Security or MP? Yep, the Navy has those programs as well. BUT, in order to qualify for those, you must first enlist, then after you make Petty Officer Third or Second Class, you have to volunteer and be selected, then sent to training. After completion of training, then you are redesignated as an MA (Master At Arms).
If your ASVAB scores are too low, or there is no billet currently available for that particular job, you will be offered something else you might be interested in, or told you will be enlisted as non designated (SN/FN/AN), and told how to try to qualify for those programs after you complete boot camp and apprenticeship training and sent to the fleet.
As far as "coming back to the ship with only boxers, ID and a smile"? Nope. That is pure fiction, because if you come back with only boxers and an ID, you WON'T have a smile, because that means you've just gotten seriously mugged.
But, if you do have a bit of game, and know how to milk the mystique of being a US Navy Sailor, you will come back to the ship MISSING your boxers, looking fairly disheveled, with a big grin on your face.
But....................that is a rare occurrence, as on a 3-5 day port visit there generally isn't enough time to sweep some girl off her feet........................unless of course you have the opportunity to go to some of the fabled ports like Australia. Palma Mallorca and Ibiza during the summer time are also good places for that to happen because there are lots of European women on holiday (which is the equivalent of the US Spring Break).
As far as the marriage thing? If you have a good strong marriage when you go in, you might be able to stay married while you are in, but yeah, spouses cheating on their husbands while they are deployed is a sad reality. In Norfolk, we called 'em "Med Widows". I also remember that in the month or so before we deployed, there was a whole bunch of people getting married, but when we came back from cruise, there was a whole bunch of people getting divorced. Me? I got married halfway through my first enlistment, and ended up getting divorced a couple of years later. Decided to stay single until I got out (either retirement or EAOS, and I stayed until I retired), and was much happier in the Navy as a single man. Yes, there are lots of women out there that like the cachet of dating a Sailor.
