Minnesota seems to have more details in how they see a militia.
What do some of your former states say about this?
I would expect though if we were being overrun by Chinese that the State Governors in question would want to arm the militia's with a little more than shotguns, 30-30s, pistols and the like. You would need much heavier firepower against Chinese armored cars, tanks, etc.
