Its meaning is clear contextually. As are most most terms we use regularly, colloquially to describe the world around us. With or without whatever sort of technical formal definition you’re seeking. I and a bunch of other people seem to have discerned it just fine. And seem to discern what is meant by that regularly, and well enough to have a conversation about it. The way this usually goes “back and forth for days” is repeated insistence that such terms are meaningless, and insistence that whatever is being discussed does not qualify because “automatic”.
It doesn’t lead anywhere because that base “well actually … Automatic” is intended to prevent it from going anywhere. Conversation does not require we predefined a legal standard. Everyone knows what’s meant when this comes up, and noone is suggesting that something as vague as “military grade” form the sum total of a legal standard. Nor even that direct military connection be a defining part of one.
I’m not saying that’s neccisarily your intent. But you’ve internalized an argument and approach from that quarter.
