I don't pretend to know what the scenario would be where I'd actually use my guns. Be assured it's a nightmare scenario and not some dispute over land use rights.

A few lone nuts would have no chance against the government. But if the sentiments and fear spread to the point that entire towns were like-minded in their opposition, you'd have a guerrilla warfare situation like we saw with insurgents in Iraq. In that situation, the government's job becomes much more difficult, and assuming carpet bombing is off the table, small arms indeed can make an impact.
