WHAM! The stock market collapses because there is no one to buy any of the stock for sale, at any price. It happens in the morning and the word gets out quickly. People know that something big is going on. By noon Eastern Standard Time the whole country is awash in the news. By two o'clock in the afternoon the big box stores are starting to sell out of groceries. All gasoline, food, and ammo are sold out that day. The unthinkable has happened. America has gone to her bunkers and awaits the anarchy that is sure to come. And the next day it begins. Those too stupid or unheeding are out and about looking for what they did not have to begin with. Violence breaks out all over the country, with warehouses in major cities being especially abused. Within a couple of days there is organized looting and robbing taking place. The bigger the marauding gang the more vicious they are. Power begets cruelty and lack of compassion.
The president has everyone in the country who wears a uniform, on alert. Troops are not put on the streets immediately but after three or four days they begin to make their presence felt. The populace is afraid of the troops at first but after learning that they bleed just like everyone else the fear starts to dissipate, replaced by a large anger. Their anger is directed at what they\ perceive as a force that is trying to stop them from doing what they must do to survive. The news reaches the country that the Mexican and Central American population of Los Angeles has gone out of the city and is looting and burning the suburbs. The race war begins. The tanks are called in to stop the burning and looting but the marauders find out that tanks may be made unbearably hot with one and two liter glass bottles with a mixture of gasoline and diesel fuel inside them and a flaming rag sticking out of the hole on top. Throw it and watch the flames start heating the steel. And this shit is going on all over the country, in every major city we have. There ain't enough troops to control the damn thing!
So what do the troops do? They pull back to selected spots and create strongholds that are damn near impenetrable. Sorta like the Green Zone in Iraq. And from these strongholds they send out patrols to areas they need to calm down and pacify. And then the fun begins.
The citizens are forced to protect themselves not only from marauders but from US troops! You can't prosecute them for anything they do in a war zone. It has been tried and it ain't worked. So now you have to defend against trained troops. What to do? What to do?
Well, the first thing you do is to pick up every goddamn weapon and piece of ammo you run across. Leave none of it. Get every rifle, pistol, grenade, and machine gun you can find. Don't leave behind any mortars or land mines either. Haul home any artillery you can get your hands on. And whatever weaponry you find that you cannot use, disable or destroy it.
Then it is time to put on your thinking cap and figure out what you can scavenge that will take out a tank or a helicopter. These contraptions will put a hurt on you that will end it for you if you don't get some means to destroying them when ever you see them. They be nasty as all get out. And they will kill your buddies too. You will end up needing ALL of your buddies, believe me. So pick up and carry home things like TOW missiles and things that look like they are Stinger missiles. I don't know, the Table of Organization and Equipment may have changed and I am not aware of it. There may be new toys in the TO and E that I don't know about but you had better learn them and learn them now while you have time to study. The bastards that will be coming after you will know the stuff by heart.
I hope that while you read this you will see the need for a group defense. Not only group defense but group food production and group building and schooling and all those things that make a people self sustained. One of the tricks employed to render us weak was the idea that we all had to have our own house and our own life and our own ways of doing things. So now we come to a place in history where we have no social cohesiveness. We are not used to working with each other. And it limits the hell out of our efforts, especially the effort to provide continuity of life. Adjust your life style to gain these advantages. And stay alive.
