Laser Cutting Creative Design Diagram | Fortress1

Fortress, a military defensive building made of wood, stone, iron, or concrete, completely or partially buried underground to defend against artillery fire and serve as a self-defense base. Commonly seen during World War I, World War II, and the Cold War. Can serve as a command center, ammunition depot, and storage facility. There are often tunnels, trenches, or transportation trenches connected, equipped with machine guns and cannons, which can defend against artillery fire and air attacks from above, filling the defense gaps of trenches. Some bunkers can also resist toxic gas and nuclear radiation. To this day, fortress construction is a relatively objective issue. In various armed conflicts and terrorist attacks, providing a safe haven that can provide reliable security protection has always been the goal pursued by ordinary citizens and even defense parties.

Kind reminder: The design drawings must be modified according to the actual type and size of materials used before use.
