That's a lot like how other NATO countries operate as well. But my impression was that the American national guard units were professional full-time units, is that not the case?
Out Norwegian equivalent (the Home Guard) consists of civilians (i.e. people with normal jobs) that train a number of times a year, some of which have their equipment at home so that they're ready to deploy on short notice. They have some coordinated training with the army, and are intended to function as a kind of "local force" in their region, with in-depth knowledge about local conditions that the ordinary army doesn't have.
Honestly, I've read a psychological study on this that basically concluded the it should be called "dadsplaining" because it's based in a natural instinct of wanting to explain things to help your kids grow.
