I've been reading a lot of posts this year regarding military service and I'm hoping that my AR brothers with Armed Forces experience can help me with advice for those considering joining the military.
First off, enlisting or joining the military through various officer programs is serious business. You should be 100% certain that you want to join. IMO, 99.9% desire doesn't cut it. The military is a life-altering experience. It might not seem like much, but 4 years without your constitutional rights is a significant amout of time. Plus, it's not a regular job - if you're late for work as a civilian you might get fired, but if you're late for work in the military you might go to the brig first and then get some type of other than honorable discharge (this might be extreme, but it has happened).
Second, when considering potential Military Occupational Specialties (MOS)think about what you want to do after the military. Think about what you're interested in and do some internet research via the various Armed Forces websites. Have some ideas and write down any questions you can think of before you visit a recruiter.
Third, don't believe everything the recruiter tells you. Their job is meet a quota while saving the ***artment of Defense money. They are not obligated to disclose information regarding enlistment bonuses, college tuition repayment programs, etc., unless you specifically ask. If you're not sure about what a recruiter is telling you, ask them to provide it in writing. If you're still unsure or have no confidence in your recruiter, contact a different recruiter. Make sure that you're getting what you want before you sign anything. Don't be an easy sell.
Fourth, study for your ASVAB (Armed Services Vocational Aptitude Battery) and try to get the highest score possible. Higher scores qualify you for better jobs. Perfect scores (99) are not unheard of - I aced mine with no sleep and a massive hangover.
Fifth, get yourself in shape before going to bootcamp. I was honestly shocked (perhaps naive) that people would show up for bootcamp with waivers for bodyfat %, unable to do 10 pushups, 10 situps, 0 pull ups, and/or meet a minimum run time. Bottom line - don't be a burden to others. If you're serious enough to sign the contract, be serious enough to show up in proper condition.
Sixth, while you're in bootcamp STAY in shape as best you can. After the first couple of weeks (when the drama of bootcamp dies down), I had to do daily physical training (PT) on my own because we only did PT once a week. Once I passed my SEAL PT test, I was able to join early morning training sessions with the SEAL Motivator at Great Lakes, IL, Recruit Training Center (RTC).
Seventh, there's no need to volunteer yourself for unnecessary jobs in bootcamp. For example, in the Navy bootcamp system, there's Recruit Chief Petty Officer (R-POC) and Assistant Recruit Chief Petty Officer (A-ROC) and those guys put up with a lot of shit. I volunteered for the Guide On position and got the PT Petty Officer position by default (I smoked everyone in the first mock PT test). Looking back on it now, I wish I hadn't because I had extra duties that contributed nothing after bootcamp. Just be a team player and help others when you can.
Eighth, arrive for bootcamp with minimal baggage. Shave your head down to stubble, don't have any facial hair, and for God's sake don't wear any jewelry (especially earrings) other than a wedding ring if you're married. Bring a decent picture of your woman or family. Bring an address book (with family and friends addresses already written in it) and small stationary set including postal stamps. Don't bring a big suitcase, don't bring porn, and don't bring your girlfriend's panties. Bring $50 bucks, a shaving razor (I brought 8 disposable razors - one for each week of Navy bootcamp), shaving cream/gel with a solid bottom (not with a gas pressure valve - for example look at the bottom of Edge shaving gel and that's what you DON'T want), a toothbrush, a tube of toothpaste to last you for at least 8 weeks, and some deodorant/antiperspirant. Dress very simply and wear a new/almost new pair of running shoes. When I arrived at bootcamp, I was wearing a pair of Levi's, a white T-shirt, a pair of white boxers, and a new pair of Nike running shoes. I had a small shaving kit with everything I listed above. After marching around the first week, my shoes were broken in and I was good to go for the runs. Plus, I didn't have to use my recruit coupons to purchase anything, including the initial haircut. During weekend liberty after graduation, I used my coupons at the base exchange to buy junk food, which I ended up selling later for cash.
Ninth, don't be foolish regarding drugs (including steroids). They do test for drugs and catch people, so make sure you're clean. A common ploy is to keep you awake for the first two days of bootcamp and then scare confessions out of people (lack of sleep induces paranoia). In my experience, there aren't that many bodybuilding physiques in the military, even in the special operations forces. For example, most SEALs are built like triathletes, not Rambo.
Finally, do what is necessary to gain advancement/promotion. For example, in the Navy, you'll have to finish your PARs (Personnel Advancement Requirements, which are necessary for all Navy personnel) as well as your rating (Military Occupational Speciality, or MOS) requirements. Increased rank means more money and more responsibility. Also, a single increment in pay grade (E-3 vs. E-4) can mean the difference between working on a shit detail and supervising a shit detail.
That's it for now, but I'd like to get input from other military vets. I'll write up a section for potential SEALs and I hope some other SOF guys will throw in their advice as well.
