How to mail a card to soldier overseas?

I want to mail a card to a friend who is a soldier stationed overseas. Do I need to use additional postage, or anything else added to the envelope?

1. no i dont think so. i think you just put the address and regular stamps.
2. Just a card, no. A package, prehaps. You would also need to fill out a customs form. Make sure the address is correct: SGT. SMITH 23rd BATTALION UNIT 2340 BOX 132 APO AE 09350 or SGT.
