The military is getting very selective now.
To join as an enlisted soldier:
You need a HS diploma. No GED.
No run-ins with the law. No drugs. No DUI.
Pass a military SAT type test
Take a physical fitness test
No medical issues. Not even a minor one. No asthma.
Military intelligence will get you a civilian job. Same with logistics and communications.
She meets those requirements, although obviously hasn’t taken a military entrance exam yet. She researched the physical fitness entrance requirements and could pass now.
