There are few countries that can match the experience Israel has in designing protective structures. Military threats to population centers along the borders forced Israelis into the field decades ago. As early as 1969, the country began gradually adapting military expertise for civilian use.
Large-scale investments in securing buildings began in the early 1970s. The primary threat was along Israels border with Lebanon, where Palestinians and Lebanese fighters manned mobile Katyusha rocket launchers and artillery batteries. The attacks led to the design and construction of protected rooms in northern Israels homes, schools and public buildings.
