Relatively bulletproof, and depending on the furnishings, darned near fireproof. Structurally strong enough to NOT collapse during earth tremors or earth movement, and an ultimate fortress in serious times of anarchy or civil unrest.
And it is entirely modular.
Five gallons of gas and a match and you'll find yourself holed up in a dutch oven.
This is a little misleading. There's an early Doomsday Prepper episode where a guy puts a hole in one with a 10/22. There's a Mythbusters episode where they prove as little as 4 inches of dirt on the top collapses the roof. The framework around the container is strong as that's what supports the stacking of them but the sides are really quite lightweight - by design. They are for shipping after all.
They are an affordable solution for many applications but they are not a fortress by any stretch. Just so everyone knows.
“Relatively bulletproof...”
It would be nice to think so, but how do you define ‘bulletproof’? ... 22LR, 9mm? When is it not ‘bulletproof’? I doubt it would stop a .45 acp or a 7.62x39...a .223 maybe...
