Establishing credit doesn't vary because you're in college, in military, etc. You want to open a couple of revolving accounts (preferably Visa/MC as opposed to store cards), pay the bills promptly each month, keep the balances at no more than 25% of the credit limits. If you do have student loans, pay them on time. Don't ignore any bills, they can turn into charged off accounts that ding your credit for 7 years. In short, build positive credit, avoid negative credit, and you'll be fine!
