Zelensky signed a decree implementing the decision of the National Security and Defense Council of Ukraine from September 25 regarding measures to build a strip of engineering barriers to ensure an adequate level of protection of cities and mechanisms for their implementation. We are talking about the so-called total protection of populated areas. According to the document, it is planned to build a system of engineering barriers necessary for the organization of the defense of cities. However, the annex to the presidential decree is marked "for official use", so the open part does not specify specific cities, a list of planned engineering structures, mechanisms for their construction and clear deadlines for the completion of the work.
