A few points. First, I said me & 4 fellow DDPers, so it'd be 5 vs 50. And think about what I said. Consider how much ammo & weapons you have within 30 ft of where you are right now. If you can't fill a dolly, I'm not sure why you're here (or maybe expand the range to 100 or 200 ft?). I'd expect you can fill the back of a pickup, at least 10 weapons and 10k rounds? And you're one person, make it 5 full pickups for 5 guys. Now let's look at Antifa, 50 guys (or identify as male??). I'd guess they might have 2 handguns and 2 boxes of ammo among the whole lot. I'll go rich & add 10 BB guns. No spare magazines: 2 guns, 2 magazines, call it 20 rounds and able to reload 2-3 times? Back to our side. Anyone here have less than enough magazines to load 500 rounds? Call it 25 magazines. This is per person. And, you have actually fired your weapons! So, anyone want to project that battle?
OK, back to scenarios. I've done a model where I've looked at smaller towns and larger cities within 100 miles. Take the population, break it into 3 equally sized groups. Assume a worst-case scenario like EMP. Group 1: head out of the town to go to family in the country (they are no threat). Group 2: stay frozen in their homes. They'll get slaughtered by group 3. Group 3 ( the problem): 1/3rd of the people go out & scavenge/kill/steal to survive, forming packs. Most will be smaller, dozen(s)? They'll first go throughout the cities (places they know) slaughtering each other. And once the cities are gutted, they'll move outward (weeks/months). Numbers: Group 1 (33%): no threat, may or may not make it. Well, let's say 5% of this group turn into Group 3. Group 2 (33%) are dead. Group 3: 33% start, let's say 80% of them get killed. That leaves 5% of Group1 (who've gone bad) and 3% of Group 3. That's 8%. Assume they'll be moving out via major highways/roads primarily. If you have a city of 1 million, that's 80k people heading out to cause trouble. Assume 2/3rds are on major roads & 1/3rd go cross-country. And assume __% are killed for every mile, this might be 5%, take your own guess. Times will be dangerous. Those 80k at 5,10,20, or 30 miles will drop to 62k, 47k, 28k, and 17k respectively. Take a smaller town of 10k and take 2 '0's off each of those numbers (620, 470...). Keep in mind, these are all the people moving in all directions. If you think you'll get 1% of the exodus, plan accordingly. And plan for your region, liberal areas will have far more cowards (group 2), and some areas like Chicago will have far more Group 3.
Ok, in these scenarios the zombies will be armed. But minimal training, minimal supplies, and desperate. A bad combination for them if you're ready.
