Zemlyanka

A zemlyanka is a type of shelter made by digging a hole in the ground and covering it with materials like wood, dirt, or metal. It's kind of like building a secret underground fort that you can hide in. Soldiers or people who need to hide from danger often use them. It helps protect them from things like bombs or gunfire by letting them hide safely underground. It can also keep them warm in cold weather because the earth helps keep in the heat. It's kind of like a special hiding place that can keep people safe and comfortable.
