Being on an open road highway is NOT good. There is no place like home. Strength in a degree of comfort. ALL of your fire power ready to go. Unless there is absolutely no way you will survive a massive attack assault.
Some gangs with guns would just bring me more weapons and free ammo. There would be body discard detail though. Like dragging your deer out of the woods on a trail bike from where your stand is.
What would blow it for us is if a concentrated high number of personnel did a pass through our subdivision. If well trained and armed division size forces made their way through here, we would be wasted. Or, a tank was sent in to clean out hot spots like us.
Set up cover to where Night vision heat sensors may not pick you up. Helicopter patrols would find a lot of us.
Do not transmit. Directional radio convergence is all too easy now. They can X you right in within minutes.
If our own military comes in to ICE down known large capacity weapons holders, that will be a real big mess on its own. But, that most likely will not happen if we are assaulted by foreign power. The military will be expended on them.
Keep your wits about you and don't over react. Conserve your resources. Stay covered. DON'T SHOOT UNLESS YOU ABSOLUTELY HAVE TO.
