SharonAnne, there's no-joy, in civilians with AR15's going up against a military company with adequate support. We were rendered harmless to the Government decades ago when the citizen could no longer possess the same weapons as our Warriors.
Ever see the youtube videos of our choppers in night action over in the sand box or Puff the Magic Dragon working out at high altitude?? Naw, we have to depend on the military top brass to take over and remove the vermin from power/office.
We can defend ourselves against like armed thugs, that's just about it as far as our ability to resist determined forces - but I'll never live under tyranny either, so if the time ever comes, I'll ride to the sound of the guns and do my very best to take as many basterds with me to the gates of hell.
We also CAN deport 15 million illegals if given the opportunity.
