"52nd Infantry Division policy at NTC forbids the use of personal cell phones in the division area of operations but we know that soldiers depend heavily on these devices for all manner of personal needs and parting with them is often socially difficult and inadequately enforced. Recently, NTC has begun purchasing the same advertising technology data used by commercial advertisers to track device locations over time. While individual identities remain masked, simple aggregated operational security analysis can quickly reveal which company or battalion is where throughout the area of operations by correlating clusters of devices with unit headquarters locations back at home station. As a recent example, data purchased by NTC showed a cell phone taking a circuitous path across the desert in excess of 120 miles per hour. Analysis of this device correlated it with an attack aviation battalion headquarters at home station. We were then able to determine the exact route an Apache took to evade OPFOR air defense systems because one of the pilots presumably carried an active cell phone in the cockpit."Click through and read the whole thing. It's fascinating.
