Doomsday Preppers: Season 3, Episode 7

3 - 7:

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.
