"...Thus, many Iraqis believed that American troops wore sunglasses that enabled them to see through clothing, and had armor vests that were actually air conditioned. When they first encountered these beliefs, U.S. troops thought the Arabs were putting them on. Then it sank in that Arabs really believe this stuff. It was a scary, or amusing, moment for many Western troops.
"However, many troops learned to live with, and even exploit, these odd beliefs. When troops at one base discovered that they weren't being attacked much, because many of the locals believed that the base was surrounded by a force field, the troops would casually make reference to their force field. They would do this inside the base if any Iraqis were nearby and especially when they were outside the wire and among the locals. This reinforced the force field myth and made the base safer. Other troops would invent new fantasies, like pretending that a handheld bit of military electronics was actually a mind reading device. That often made interrogations go much quicker. Not all Arabs believe in this stuff, and those that didn't and worked for the Americans, often as an interpreter, could only shrug their shoulders when asked about it."
