Pentagon disables ad tracking on troops’ devices
The change covers military iPhones, Android devices, and Windows PCs after concerns that app location data could be used to target U.S. troops.
The U.S. Department of Defense has disabled advertising tracking on troops’ phones and computers to make it harder for adversaries to use location data against them. The change, described in a letter shared with Senator Ron Wyden, affects government-issued devices across several branches of the military. It ties a familiar consumer-tech feature to a much more serious risk. In a military setting, data used for ad targeting can also reveal where service members are.
Military branches disabled tracking on government devices
According to the letter, the U.S. Army, Air Force, Navy, Marine Corps, and Special Operations Command have all switched off advertising tracking on their government-issued devices. The protections apply to iPhones, Android devices, and Windows computers managed across the federal military enterprise network.
Reuters first reported the news and the letters. As IT-PUB News notes, the protections were put in place earlier this year, while the Air Force told Wyden it made its changes more recently, in July.
This does not appear to be a new public policy rollout so much as a security measure the military has already carried out internally. The letter shows the Pentagon was responding to a specific threat: location data collected through apps can be sold on the commercial market and then used for purposes far beyond advertising.
Why location data became a military security issue
The goal of disabling the advertising ID is to make it much harder to identify a person through the location data linked to their device. When the advertising ID is turned off, that data blends in with data from other devices that have also disabled tracking, making any one user less visible.
For troops, that matters because hostile governments and other adversaries could use commercially obtained location data to target them on the battlefield or on military bases. The issue does not begin with military networks themselves. It starts with apps on phones, where location information can be collected, shared with third-party companies and data brokers, and then resold.
Wyden raised the issue earlier this year in a letter to U.S. military leaders after finding that unnamed foreign adversaries had targeted U.S. troops in the Middle East using commercially obtained location data. That pushed the matter into the open and made clear the concern was not theoretical.
Wyden says the step helps but does not close every gap
Wyden, a longtime privacy hawk on Capitol Hill, called the military’s move to reduce advertising tracking commendable. But he also warned that the risk has not been fully removed.
His concern is that personal devices carried by troops and contractors onto military bases could still expose service members and facilities to attacks. Turning off tracking on government-issued hardware helps. It does not necessarily shut down every path through which location data can leak.
That distinction matters. The military can control the devices it issues, but it has far less direct control over private phones people bring with them. The source does not say the Pentagon has addressed that broader problem, only that it has disabled advertising tracking on the hardware it manages.
App data is not used only for advertising
The episode also points to a broader tension around location data. Information collected through apps is often treated as a routine part of the digital economy, supporting targeted advertising and other commercial services. But the source says the U.S. intelligence community and the FBI have confirmed they buy this data for surveillance and intelligence collection without a warrant.
That makes this bigger than a single Pentagon measure. The same stream of data can be used by marketers, brokers, intelligence agencies, and hostile actors. For service members, that creates both a privacy issue and a safety risk.
The Pentagon’s move suggests at least some government agencies now see ad tracking as more than an annoyance. In this case, it is a security vulnerability. The letter shared with Wyden shows that concern has already led to concrete changes across major parts of the U.S. military.
The source does not say whether similar protections will be expanded further or whether the military plans to deal with personal devices in the same way. But it does show how a feature built for advertising has become part of a national security debate.
