Not to downplay the reality of the situation here, but being not qualified in this case just means not being able to walk into a recruiting office and sign a contract without a waiver. The military processes tens of thousands of waivers every year for past legal infractions, tattoo policy exemptions, medical history stuff, etc. Anyone currently taking something like ADHD medication who isn't willing to stop receiving treatment for the condition is ineligible for instance.

It's kind of asinine that one can be demonstrably stable over a long term and do all sorts of things operationally in the intelligence community, but could not even become a 92G (culinary specialist) in the Army.
