US military disables ad tracking on troops' devices to prevent targeted attacks

Location data from apps posed risks to service members' safety on bases and battlefields.

1Military-wide tracking removal

The US Department of Defense disabled advertising tracking across all government-issued devices used by Army, Air Force, Navy, Marine Corps, and Special Operations Command personnel. This includes iPhones, Android devices, and Windows computers managed through the federal military network. The change came after Senator Ron Wyden raised concerns about foreign adversaries exploiting commercial location data. Reuters reported these protections were implemented earlier in 2026, with the Air Force completing its changes in July.

2Security threat background

The decision follows discoveries that hostile governments were using commercially available location data to target US troops in the Middle East. Mobile apps routinely share location data with third-party brokers who sell it on commercial markets. Wyden, a privacy advocate, found that unnamed foreign adversaries had successfully used this data to track military personnel. While the government-issued device changes help, personal devices brought onto bases still pose potential security risks according to officials.

3How tracking works

Advertising IDs on devices allow apps to collect and share precise location data with third parties. When enabled, this creates unique digital fingerprints that can identify individuals. By disabling these IDs, military personnel's location data becomes anonymized, blending with all other users who've disabled tracking. This makes it significantly harder for adversaries to single out specific service members based on their device data patterns.

4Intelligence community paradox

While protecting troops from foreign tracking, US intelligence agencies including the FBI continue purchasing similar commercial location data for surveillance purposes without warrants. This creates a paradox where the government restricts tracking for defense while simultaneously using the same methods for intelligence gathering. The practice has raised privacy concerns among lawmakers, though agencies argue it's essential for national security operations.

5Implementation timeline

The military began rolling out these protections earlier in 2026 after Wyden's warnings. Different branches implemented changes at varying paces, with the Air Force completing its transition in July. The Navy, Marine Corps, and Special Operations Command followed similar timelines. This staggered approach allowed each branch to test the changes while maintaining operational continuity across their respective device fleets and networks.

6Technical execution

Disabling tracking required coordinated changes across the military's enterprise device management systems. For iPhones, this meant modifying mobile device management (MDM) profiles to restrict advertising identifier access. Android devices required similar enterprise-level configuration changes. Windows computers in the military network needed group policy updates to block advertising tracking at the operating system level across thousands of devices.

7Ongoing vulnerabilities

While government-issued devices are now protected, personal smartphones and tablets brought onto military bases by troops and contractors remain potential security risks. These devices may still broadcast location data through various apps and services. Wyden has called for expanded protections to address this gap, noting that adversaries could still potentially track movements near sensitive facilities through commercial data from personal devices.

8Broader implications

The military's action sets a precedent for how organizations handle location privacy in high-risk environments. It highlights the national security implications of commercial data brokers' practices and may influence future legislation around data sales. The move also demonstrates growing awareness of how seemingly benign digital behaviors—like using apps with location services—can have serious real-world consequences for personnel safety.
