Hi, my name is Sierra, and I would like to join the Army as a Combat Medic.?

My husband is an E6 in the Army and he is Feild Artilery. He wants me to get attached to his brigade. My question is if I get attached to a combat brigade ( which is what I want) if I deploy will I be able to leave the FOB or will I be put in an Aide Station? Any advice would be greatly appreciated. Thanks.
