If your boss tells you to wash their personal car, thats an illegal order and you dont do it.

If you really wanted to use the military, you would just drop anti personnel cluster bombs. That would do any crowd in.

Ukraine has shown that Armour is heavily vulnerable. And tanks are too heavy for the road anyway, it would be wheeled vehicles only.

That was partially just a result of the NG having rifles but not the less than lethal tear gas and stuff now.
