If by "anyone" you really mean "anyone," then no. There'll be a mandatory physical exam and a background check, both of which will out you, and a medical history questionnaire that you'll be legally required to answer truthfully.
If by "anyone" you mean "the people I'm going to live and work with," then likely yes, but you should talk to a recruiter about it. Tell them your situation - you'll have to out yourself during the enlistment process anyway, so might as well out yourself to the recruiter early and get all the information you can.
