MARTIAL LAW – is the imposition of direct military control of normal civilian functions of government, especially in response to a temporary emergency such as invasion or major disaster, or in an occupied territory. Martial law can be used by governments to enforce their rule over the public.
The army will be able to confiscate anything that they decide they need. They will confiscate guns, ammo, food storage, your garden, and water storage. There may be other things that they will confiscate. And if they take so much that your family can no longer survive, then they will load you and your family up and take you to a FEMA concentration camp, where you will be a prisoner.
Ways to avoid this are; home canning your food. Having farm animals. Keeping bows and arrows for hunting on hand. Having a lot of somewhat unhealthy but filling and high calorie items for your food storage. Such as Ramen noodles. Home vacuum seal food. They most likely won’t take anything that you vacuum seal or can at home because it could be contaminated. Also fill up your own water containers for water storage.
