For direct acessions into the Supply Corps, you are probably better off talking to an officer recruiter to determine what field your degree should be in. If you want to lateral transfer to Supply from another community, then there is no hard and fast requirement. However, this is not to say that the community won't have a preference. My advice is to do two things. One, talk to the officer recruiter as stated above. But also, get in contact with the new acessions officer. The link below should help you along in that direction.
