ELI5:Modern Militia Purposes?

What do modern militias do? I'm referring to state militias, but not the National Guard. Are they just for natural disaster relief?

The are a remnant of an earlier time.  The truth is they aren't all that important, but many states feel strongly about maintaining their right to have one (Which is the true point of the 2nd Amendment).

In theory, in the event of an invasion or the like they would join the fight.  The thing is, that is also what the National Guard and the regular military is for.
