 @7c55c76e My reading of "keep and bear" is that certainly all weapons that can be carried and operated by an individual are protected. Modern machine gun -yes, RPG yes, shoulder antiaircraft yes, armed drone yes,... where I would accept SCOTUS ruling is anything larger, for me that is the real gray zone (at the Founders time people owned cannons...) and as such for expert readers 

 @7c55c76e if the right pursued the 2nd amendment as aggressively as the left pursued the 1st amendment, citizens would have personal nukes.
