I hope Dallas taught you an important lesson: you’re outgunned. On your way to the gun store and shooting range, consider you can’t buy enough armor to protect yourself from a robot or drone. Even a well-trained sniper can’t hold out. How long would the Oregon wildlife refuge occupation have lasted?
I assume you’re searching the Web for info on IEDs, but the Feds have learned a lot overseas. That tech and info has come home. Good luck sleeping tonight.
