During Nato's Exercise Ramstein Flag, personnel faced having their aircraft jammed with pop music, including songs by Britney Spears and 7 Nation Army. Experts in electronic warfare played tracks to simulate enemy interference during the exercise in the Netherlands. The purpose was to familiarize personnel with the concept of having their communications jammed. Interfering with communications is a normal part of training scenarios, with music used to jam frequencies. Military forces have a history of using music as a tool in various situations, from breaking down detainees to influencing diplomatic standoffs.
