I was army, Basic was a lot easier than i expected, its physically demanding sure.. but its more mental then anything. There is yelling, cussing, spitting, and a few of us got punched in the stomach once or twice, they are not suppose to hit the privates, but i was grateful my drill sergeant cared more about turning us to soldiers than following the rules. which in my opinion get softer and softer each year. MREs are not all great but its food and when your hungry the taste is not the most important thing. After basic if you go to a state-side duty station its pretty much a regular job with some exercising in the morning. Deployments are different for everyone and i dont really like talking about mine, but you take the good with the bad, despite my injuries i wouldnt trade my service for anything in the world, im proud of my scars.
The worse part of basic to me was the gas chamber... that was no joke HELL. I thought i was dying, the gas was burning right in front of us and the smoke was so thick you could barely see your hand. They make you say your name/rank/social... but you dont get passed your name, once you breath that CS gas in you will feel like your going to die. You will be ok in the end, but there is nothing i can say that will make it any easier... IT SUCKS.
Oh yea one piece of advice... We were not allowed any type of sweets during basic.. But one day the drill sergeant told everyone they could have 2 bowls of ice cream.. Now after about 5 weeks of hell, we all ate that ice cream like it was the best thing in the world.... If your drill sergeant does this, just say your lactose intolerant. After the ice cream they made us down 2 canteens of water in less than 5 minutes and then run until every single person that ate ice cream has thrown up.
Ok lets get to some of the fun stuff, plenty of people will tell you the bad and "responsible" stuff but there is a lot more to it than just that. Obviously it will depend on your unit... but if its anything like mine...You will get the opportunity to see and play with some awesome stuff, if your single you will party harder than you ever imagined, in the barracks just imagine a frat house on gameday... damn near every day. We would drink like fish, go after girls like they were going extinct, and fight together as brothers. You form bonds as strong or stronger than blood, you might argue and even fist fight others in the barracks at times, just like brothers do at home, but the moment anyone else threatens any of the team... you become 1 and fight till you drop. You will have some of the best and worse times of your life, but the memories and bonds you will form will be everlasting.
I wish you luck, dont put too much worry into basic. as others said just keep your nose clean, mind your own business, and never quit and you will do fine.
Thank you for your decision to serve.
