ray machines, such as the Fox-Ray used by the air force, can check what is inside bags and packages. They are linked with computers that instantly tell what kinds of materials are hidden, Harbi said. Saudi airports and seaports and the national airline are already using these sophisticated X-ray machines, according to Harbi. The Coast Guards and the Marines have exhibited underwater fighting equipment, such as diving suits that enable coast guards and marines to stay underwater for long periods. Anti-bomb suits donned by bomb squads while diffusing bombs and equipped with anti nuclear, biological and chemical fallouts are also on display. The Kingdom has come a long way in the fight against terrorism, and while there are no conflicts involving territories where Saudi security forces are expected combatants, the battle against terrorists is now a priority, hence we have these high-powered machines and equipment, Qahtani said.
