A coworker at a civilian job once told me that "We don't need a military, I'll just shoot'em if they come to my door."I'll take Home Field Advantage any day of the week. If they are at my door it's only after nukes dropped on theirs...
...unless the government let them in though the back door....
I laughed and told him that your neighborhood would be shelled and then if your house still exists, an RPG will be fired through a broken window that will make you tone deaf if not killed followed by 12 heavily armed troops firing bursts before entering every room.
He looked at me in shock and walked off never to bring up the topic again.
