>>7402749AF enlistment process is about the same as any other branch. Just make sure it's clearly communicated to your recruiter that you want a specific AFSC and not some general contract. If your ASVAB is high enough they'll gladly accommodate you.
But also keep in mind that whatever job you go for will impact the amount of time before you actually ship. If you try to specifically get a niche specialty, it'll take longer than if you went open general or something.
