if every gun owner can tell me his squad's commander's name, and whose the platoon leader and company commander, and how often they drill and how often they go for shooting practice, and who's responsible for kitchens and food supplies and cars and fuel and what is their designed network of communication - all of which can be organized using civilian supplies only, but be ready if the "militia unit" is ready, then I'll say, okay man, keep your gun.

You lost me somewhere in there. I own several firearms. I go out target shooting/practice quite often. I am not part of a militia but that term has a much different modern usage than that used by my constitution.

of which can be organized using civilian supplies only,

Not true at all. In fact, quite the opposite is true in the country. There is a fair amount of cooperation between civilian and federal/state military assets but they also are often quite separate from each other.
