Just another reason why community is so important. That's what community and alarms are for, if the enemy is already on your doorstep, you've failed. It's about securing your whole community, first and foremost. Not everyone will be a fighter but, everyone no matter how young or old, can be a watcher and a source of information. Add radios to the list for that reason. Comms are another important part of early warning - example, "hey, we have reports of hood rats in the area", send out a recon/ambush patrol, etc! I assume OP being airborne infantry doesn't need any clarification on that.
I was talking more just general preparedness. I feel like I have a whole host of other issues if it were SHTF. I’m thinking bad storm, the issues like with southern pines, NC scenario, another covid BS. Stuff like that.
I honestly feel like I could handle a small threat better than a more likely situation like a prolonged power outage or just being over all more self sufficient, hence my original question.
