Abstract: A wall of, for example, a bombshelter or armored vehicle, is provided with an inner and outer armor spaced from each other. This armor protection is designed to provide a deflection, respectively destruction of an impacting projectile as soon as the projectile nose has penetrated the outer armor. The arrangement is designed to permit only a relative minor destruction of the outer armor in the impacted region, so that those regions adjoining the impacted region maintain their protective structural integrity.This object is achieved in that in the partial chambers which are divided by transverse walls defining closed intermediate chambers between both armors there is disposed a material insert which explodes or bursts as a result of the penetration of the projectile, for example, a material insert consisting of an explosive, glass or ceramic material. The outer armor consists of plates which are overlappingly arranged at one of the adjoining sides and which swing outwardly.

Abstract: Structures are constructed and arranged on a camp site to provide shelter to evacuees seeking survival, as a GROUP, in case of a nuclear attack on or near their city. The construction, disposition, arrangement and shapes of the structures are such that people inside these structures are not affected by the blast of the nuclear explosion, for peak overpressure levels well above those which conventional structures cannot survive. The structures and the camp site are equipped to provide the elimination of fallout dust in a short time so as to bring the total exposure of the evacuees to radioactivity levels low enough to be safe, until the radioactivity within miles has decayed down to levels acceptable for long time exposure. The sheltering structures are interlinked to provide a quasi normal indoor way of life during the period of necessary confinement of the evacuees, so that no evacuee feels the urge to leave the protection provided within the compound against the surrounding grounds radioactivity.
