I too was raised with a gun in my hand from the time I could walk but our armed forces have so many high tech weapons (some of which I helped develop) that directly shooting at us and engaging in man to man combat will be the last thing they do.
Since they, and many here on FR think that an individual does not, and should not, own AT and AA missiles or machine guns then we have already lost most of the war against their Communism. Our founding fathers did not write in restrictions as to what types of weapons we could have, not because they only knew about muskets and such, but because they knew that we needed to be armed with the necessary equipment to keep a corrupt government at bay.
Call me crazy but I think leveling an urban neighborhood with a C-130 or an A-10 Warthog in order to root out the "redneck" living on the cul-de-sac will be a bad PR move.
