Outside of ALL of the excellent information from the SME's here. Another option (and I'm pitching the branch a little, yes) is CA. If you want Ranger, AASLT, BAC, HALO, SAPPER, while serving in a TPU status, you CAN get it in a Civil Affairs unit. It is however, a SOCOM community as we are a FAD 1 BN and do not fall under USARC. If you come to a CA team you will have the P identifier coming in. Everything else, is "earned" as you become more of a proffesional and more of a SME/team Leader etc... with experience. Hope this is another option for you.
