The Afghans have automatic rifles which are not crippled to three-shot-burst like civilians in the US are allowed to have. They also have anti-aircraft missiles, MANPADs and the like. And still, they cannot do anything against the drones.
Remember this, and you’ll see what a truly slippery slope it is when a government can wield combat drones against its own population.
A true reading of the Second Amendment cannot allow for restrictions against what a free citizen can possess to check the balance of power against the government. Even if that means private ownership of combat jets.
The Constitution explicitly recognizes the private ownership of what were basically battleships in their day. Letters of Marque and Reprisal authorized private citizens to go after Muslim pirate/slavers (The Barbary Coast Pirates... "To the shores of Tripoli").
To go after those pirates and their trans-Atlantic ships, one would need... anyone anyone? Bueller? Bueller?... yes, that's right, ships of their own, of equal or greater size and abilities.
It is not weaponry that has changed, it is our culture and what we have allowed our leadership to do to us.
I’d like to know where I can just go out and get a selective fire weapon with the kind of ease you imply. The only kind of rifle I can get that comes remotely close (without huge fees and wait times and extensive background checks, etc...) is a semi-auto. One trigger pull one bullet, lather, rinse, repeat.
Civilians can’t just go out and get a selective fire weapon, which includes full auto and 3 round burst. Those are true assault weapons, not what is commonly available in the typical civ AR platform.
