Questions about joining the military?

[Matt]

So I have watched a lot of war movies recently (Full Metal Jacket, Black Hawk Down, Saving Private Ryan) and I know what you see in the movies isn't real but it has still raised a number of questions about the military to me. I am only 15 but i am starting to plan for the future and my older brother was in the air force and that seemed to work out rather well for him. As far a current skills go, I am well educated and I do very well on tests, I have tons of experience with computers (I'm sort of a huge geek), I am an excellent shot with pretty much any rifle (pistols not so much but I'm still decent). I'm not in the CAP but I still know the fundamentals of flying a plane and have logged close to 100 hours on my simulator in planes ranging from small Cessnas to the F/A-18 Super Hornet and even some time in larger planes like the C-130 Hercules and Boeing 747. I can also fly pretty much any helicopter. I am disciplined and willing to receive orders. However I am not in the best of shape (I weight about 200 pounds) and i can't really run very long distances. I can however run very quickly for a very short distance. Based on these skills and weaknesses, I would think being a pilot in some branch would be my best bet. I feel that as a pilot I could serve my country well, but I doubt with my physical short-comings if i could make it through basic training. Also in the movie Full Metal Jacket they made it look like you didn't learn most of your necessary skills in basic training. It seemed all the other men besides private Piles knew how to make a bed military style and knew the various marching commands. During the marching scenes in the movie I have no idea what Lee Emery is saying to the men. He just sort of sounds like he yells incoherently and everybody does the same thing. Is there any place I could get a list of these commands before going to basic? I tend to understand people better if i know what to listen for, like i can hear the lyrics of a song more clearly if i know what they are. Does it sound like the military is for me? The way I see it I have several skills so I have plenty of options and I would like to look into them all.
