Dear little one, do you know what a house is? Well, a B hut is also like a house, but it's a temporary shelter that people use when they are out in the field for work or camping. It's made with metal walls and a roof that goes over the whole thing like a blanket, so it can protect people from the sun, wind, and rain. The B hut is usually small and simple, but it can be set up very quickly by people who know how to do it. It's a good thing to have when you need a place to stay for a short time, just like a tent or a cabin.
