I went to MEPS last year (November 2012) in Houston, TX for the Navy. You will wait in lines, pee in a cup, do funny stretches in your underwear, test your vision, hearing, body mass, scrotum, anus, and a few others. (they look at your package and bum for all of 3 seconds) You will be mixed with all branches of hopeful recruits. It's nothing to be worried about. Just don't be immature and talk about partying or any irresponsible habits you may have/had. You are being watched and listened to at all times. Do your best to maintain a positive facade for the 8 hours that you are in the MEPS offices.
There are signs all over the walls/doors saying that and false statements concerning your medical history, drug use, etc. are subject to a $10,000 fine. This may be true, but if you have nothing to hide don't let it worry you. The questionnaire has loaded questions, such as "how many times have you smoked marijuana?....1, 2 ,3 or more times?" and then there is a blank line. Pencil in that you don't smoke, even if you have done so a few times. There is absolutely no way for the military to know if you have done so or not, unless of course if you tell them, which they will try to pressure you into doing so anyways. If you say yes, you remain a civilian almost guaranteed. Unless of course, those two slips in judgement were enough to derail your life. Then by all means, let them know haha
I've had broken bones that I didn't list, a hernia, as well as a few stitches here and there. It's not worth mentioning unless you have lasting physical handicaps from these events. I'm not saying to be your own doctor, but use your best discretion. Your recruiter will most likely tell you not to list these items as well (mine did...about 6 different times). If you do list them, every single item
will need a waiver from your prior or current physician, which takes months. not to mention your recruiter will hate you and pretty much ignore or put-off his efforts towards trying to enlist you.
I went against my recruiters advice (I was going for Navy Nuclear Program btw) and listed a benign brain tumor that I had 20 years ago (I was 23 at the time). I've had no side effects, or handicaps. If anything I would say I am well above the curve when it comes to my noggin (156 IQ, give or take). This surgery eventually caused me to be PDQ'ed (Permanently Disqualified) after waiting four months for the waiver to be reviewed, despite having a bachelor's degree in Biology and scoring in the 98th percentile on the ASVAB. I would have not mentioned the tumor, but I have an 8 inch surgical scar on my head from it, which is rather hard to miss once all 14 inches of my luxurious hair was shaved off. They would not have accessed this medical record unless it presented an obvious handicap while i was in bootcamp (they watch out heavily for insurance liabilities during bootcamp) or resurfaced while i was enlisted some time down the road. Hence, my advice to not mention it. Yes, it is lying, but you are asked to list EVERY hospital visit since you were born, no matter the severity. This would be an impossible task and no one would ever admitted after all of those waivers stacked up. Airforce is one of the branches that is heavily downsizing, or at least limiting the number of new recruits. Any reason to drop you will be used.
I almost sound like my recruiter, "Say no to everything." haha, don't do that, but be smart about what you list.
I'm now applying to nursing school. Be sure to have a Plan B. I didn't and I was absolutely devastated.
