Congrats and thank you!!
I spent 10 yrs in the Army and I am glad I did.
Like with anything in life, you get out what you put in.
I started as a E-1 then after hard work, college, etc, I came out as a 1st LT. Other bums who where in longer than me were still only E-5.
Ah good ole Fort "Lost in the woods"
Remember, dont be first, and dont be last:)
Best advice I can give is to save your money while you are away...Everytime something looks good to buy, remember the striper

Good Luck!
