“In May [12] 2007, British commandos killed the Taliban’s senior military commander, Mullah Dadullah, a successful operation directly attributable to a systematic effort by British and American SIGINT [signals intelligence] collectors to track his movements in Helmand Province [Afghanistan] by monitoring his satellite phone calls and those of his brother Mansour, also a senior Taliban field commander.”
