Oh, that's a local volunteer militia. Much different than the organizations at play here. They usually don't have much to do with the state, except that the state govt can choose to activate them to assist with emergencies; in which case they'll be compensated by the State for their time.

They're basically like the Reserves for the state's National Guard. They fill in as requested, but don't have much to do but train. I'm pretty sure Trump can't activate them, as they're strictly a local militia. Federal government has no authority over them.
