I’m wondering specifically in a SHTF scenario what are your plans. For example; five people are approaching your location, 3 identified with firearms. They are 100 yards away and walking to your location checking each building. They station a sentry outside each time to watch. You are not observed yet but pulling away is not an option in this scenario. You’re not certain of your numerical advantage in fire power. Are you going to warn them away verbally, shoot a warning or engage them in a fire fight?
