Unfortunately, while the tactics may be little changed since the 18th century, the techniques most assuredly have. Patriots won't be facing soldiers in bright red coats armed with muskets and bayonnets. All the technology of the contemporary military will be brought to bear--sophisticated surveillance and communication gear, armor for soldiers and vehicles, and a versatile array of weapons. The government will have the advantage unless/until the grid goes down and both sides have to adapt to the sudden loss of communication and supply.
Pray it doesn't come to this.
