With the developing production systems, it is possible to produce more economical, faster, more useful, healthier, and more durable structures. Modular army building is one of them. Prefabricated and container structures are used in this area. Prefab military structures, such as prefabricated military shelters, are very preferred systems. Karmod, with its experience in the building sector, has been producing special products for the defense industry recently. Accordingly, Bullet Proof Armored Cabin and Bullet Proof Visor developed in Karmod R&D are among these products.
