I know someone that felt the affects of this 'under-the-table' dealing firsthand. This person happens to be the company commander of an aviation unit consisting of Apache Longbow gunships. Due to the Iraqis acquiring some type of GPS scrambler, he had his guys purchase back-up portable GPS devices prior to deploying.

Pretty dark stuff once you know someone's life is at stake...I guess money makes the world go round, huh?
