It turns out that not all preppers are ready to shoot anyone who comes near their stash of canned beans. In "Doomsday Preppers: We Are the Marauders" (Tues. Nov. 12 at 9:00 p.m. on Nat Geo), we meet Kevin. In this exclusive clip, we discover that he actually has an inclusive, community-based plan for when armageddon hits. That's the good news. The bad news is that, unless you're in Costa Rica, you won't be able to hit him up for stuff. 

Of course, Kevin is the exception. While many preppers believe defense is the best strategy for surviving a Doomsday scenario, one family in Tacoma, Wash., is banking on a good offense. Tyler, his wife and his cousin have assembled a group of like-minded, would-be marauders from their neighborhood in preparation for a catastrophic domestic terrorist attack. They have only six months’ worth of food because they plan on taking what they need in order to survive — and to stay safe, they’re developing the ultimate suit of armor. The homemade protection will be bulletproof, lightweight and stronger than anything sold in a store — hopefully an ideal defense mechanism if martial law is enacted and civility goes out the window.

Meanwhile, our pal Kevin believes that cooperation and sharing among neighbors is critical to survival. He’s decided that the best way to bug-out is to flee the country — that’s why he moved his family from Kansas to Costa Rica. In an effort to become more self-reliant, Kevin is planning to ramp up his food production with the ultimate aquaponics system and, if all goes as planned, he’ll survive Doomsday with a never-ending supply of fresh fish and vegetables.
