I went to Army Basic Training 2 years ago. I enjoyed it. It's alot of fun and you do stuff you cant do anywhere else and you meet good ppl. I dont know how Navy boot camp is but i figure they are mostly the same to start out with.
My training was 10 weeks + 1 week of getting shots and making sure you are who you say you are. We camped in the woods for a week. Learned about how to handle and fir weapons and actually got to fire the standard rifles and some weapons. DId exercise everymorning at 4am till 7am except on Sunday. The food was......cant describe it you'll see for yourself. They had fun obstical (SP) courses the reminded me of Ninja Warrio on G4. THe only thing I was worried about was the Gas Chamber where they put you in a room of CS Gas which burns skin on contact, where they make you test your gas gear to see if it works. But overall is very fun.
It's more of a mental challenge than a physical one cause yeah you run alot, do push up, and other stuff like that but you are constantly getting yelled at. The Sgts in charge will get up in your face and try to make you hit them. I mean if you've never been yelled at by your parents then it'll be something new to you but to me I've been yelled at worse by my mom so the mental stuff wasnt hard at all. Just look at it this way.......it's like a live action game of Call of Duty except your training and not in war, that's what I did and I had fun.
It'll be fun no need to be scared or nervous. Good luck.
