“You have to be offered something to refuse it.”
No...you have to sign up, and apply. Then, you have to prove yourself.
They don’t “offer” anything unless, and until, you’ve passed muster.
When you graduated High School the military was begging for you.
You rejected the military, even though you were some kind of female warrior/athlete freak "In my youth there were God Damned few males who could better me. They tried and they failed. Like you they were not only ignorant they were arrogant. But me being a God Damned cunning female managed to beat them at their game not only physically but mentally and emotionally as well. They went home with their tales between their legs."
Now you still want the worst for the American military.
