The study is practical, and uses descriptive, correlational- agreement method and study of scientific documents with Contextual approach. The data for this study have been collected through the library search (books and technical articles), and internal and external databases. The results show that despite the arrival of new technologies and equipment in battle, Distance still act as a major barrier in disappointing the enemy. International Journal of vital centers in central region and away from the borders, International Journal of vital centers in central region and away from the borders, is an important passive defense.
