Command posts are the "heart" of every military operation, hence it is important that command post facilities are adequate for planning and conducting the operation. Throughout history, various systems of fortification and construction of permanent type facilities have been applied, so depending on the method of construction, permanent type buildings can be modular, prefabricated or built on site. What are the systems most used and what do they all involve? What should be considered when planning and building military facilities? What mechanization is used in construction and what should be included in the calculations? What resources are needed? These issues are only part of what must be considered in the planning, organization and implementation of construction works and the construction of military facilities. After the completion of the construction, the engineering works do not stop, they are continuously carried out through the facilities maintenance and masking. Since command posts are high on the enemy's list of priorities for destruction, the secrecy of the exact position of the object is crucial, so it is most important to pay close attention to camouflage and camouflage discipline.
