But the data also offers a mine of information to anyone who wants to attack or ambush U.S. troops in or around the bases, Schneider said, including patterns of activity inside the bases. Many people wear their fitness trackers all day to measure their total step counts, and soldiers appear to be no exception, meaning the maps reveal far more than just their exercise habits.
Lines of activity extending out of bases and back may indicate patrol routes. The map of Afghanistan appears as a spider web of lines connecting bases, showing supply routes, as does northeast Syria, where the United States maintains a network of mostly unpublicized bases. Concentrations of light inside a base may indicate where troops live, eat or work, suggesting possible targets for enemies.
You're thinking big picture. Patterns of life, places of activity, patrol routes.. All incredibly useful information. It takes huge amounts of manpower and time to collect this information, and we just went up and handed it to anybody with an internet connection
