Anti-terror tourism proves a hit in Israel

Anti-terror tourism is taking off in Israel, where punters can exchange cold harsh cash for a role-playing, terrorist-fighting adventure. Caliber 3 opened its doors in 2003 as a training camp for security professionals, but the company has since diversified its portfolio and is now offering anti-terrorism courses, during which travelers are schooled on the basics of weapon handling and the Israeli military’s martial art, Krav Maga. The company currently pulls in some 25,000 anti-terror tourists a year. So if you’re feeling a little too relaxed after floating around in the Dead Sea, a visit to Caliber 3 might be the perfect pick-me-up.
