US-Israel-Iran War Latest Live News: A smartphone carried by a US service member can reveal far more than messages, calls or app activity. Location information generated quietly in the background can potentially show where a person is, where they travel and how often they return to a particular place. That has become a growing security concern for the US military as American forces operate in the Middle East.
The US military has now taken steps to reduce that risk by disabling advertising trackers on a range of phones and computers used by its personnel. The move comes after reports that commercially available location data had been used to target American forces in the region.
The action was disclosed on Friday through letters released by US Senator Ron Wyden, and statements from military officials provided to Reuters. The disclosures show that several branches of the armed forces have already moved to limit advertising identifiers on military devices.
US-Israel-Iran War Latest Live News: Why is the US Military Blocking Ad Trackers?
The main concern involves the large commercial market for location data.
Advertising companies routinely collect information from phones, computers and applications. Data brokers can then combine, analyse and sell information about users and their devices to other customers.
In some cases, these datasets can provide information about where a device is located and how it moves over time. That creates a serious security problem when the device belongs to a soldier stationed near an active conflict zone.
The US government has previously been warned that foreign adversaries were using commercially available location information to target American service members in the Middle East. Lawmakers said the issue represented a national security threat because adversaries could potentially obtain sensitive information without breaking into military networks.
US-Israel-Iran War Latest Live News: What Are Mobile Advertising IDs?
Mobile Advertising IDs, commonly known as MAIDs, are identifiers associated with mobile devices.
Advertising networks and applications can use these identifiers to recognise a device across different services and build information about its activity. When combined with location information, the data can provide a picture of where a device has been and where it is moving.
For ordinary users, this technology mainly supports digital advertising and measurement. For military personnel operating in a conflict area, however, the same information can create an unwanted trail.
Disabling the advertising identifier can make it harder to connect commercially collected location information to a specific device or individual.
US-Israel-Iran War Latest Live News: Which US Military Branches Disabled the Trackers?
The Air Force told Wyden that it disabled advertising identifiers on computers and mobile phones about two months ago.
US Special Operations Command separately said it had “recently” disabled the identifiers on its Windows devices.
The Army told Reuters that advertising IDs connected to mobile devices had been disabled earlier this year. The service also said the identifiers had been blocked on Windows computers since before 2021.
For Android and Apple mobile devices, the Army said advertising identifiers had been disabled by default since at least February 2026.
Similar letters from the Army and Navy also said advertising IDs had been disabled on military devices, although the Navy did not provide a specific timeline.
US-Israel-Iran War Latest Live News: Ron Wyden Pushes Pentagon Over Location Data
The latest disclosures came after months of pressure from Wyden, a Democratic senator from Oregon.
Wyden and Republican Representative Pat Harrigan called on the Pentagon on Friday to examine whether the military has done enough to protect service members from the commercial location-data market.
Wyden said the military’s efforts “have not been effective at neutralizing this threat”.
Harrigan said US adversaries “should not be able to pull out a credit card and buy information that helps them track American troops”.
The lawmakers’ concerns go beyond advertising identifiers. They want the Pentagon to examine how commercially collected information can expose service members and military facilities.
The Pentagon said it would respond directly to the lawmakers.
US-Israel-Iran War Latest Live News: Why Commercial Data Is a Battlefield Concern
The threat is different from a traditional cyberattack.
An adversary does not necessarily need to hack a military computer or break into a Pentagon network if useful information is already available through commercial channels.
A dataset purchased from a broker could potentially provide information about device movements. When analysts combine that information with other public or technical data, they may be able to identify patterns connected to military personnel or facilities.
That possibility has become particularly concerning as US forces operate in areas affected by the conflict with Iran.
The issue also demonstrates how technology originally developed for advertising can create unexpected risks for national security.
US-Israel-Iran War Latest Live News: Turning Off Ad IDs Does Not End Tracking
Disabling advertising identifiers can reduce one method of tracking, but experts warn that it cannot guarantee complete privacy.
Zach Edwards, co-founder of privacy ad-tech company Decryptads, said disabling MAIDs on military-operated devices was “definitely a positive thing”.
He cautioned, however, that troops could still potentially be tracked through other methods, including applications or by combining technical device information with network and location data.
That means a device could continue producing information even after its advertising identifier is switched off.
Other signals, including network connections, application data and technical characteristics, could potentially contribute to a broader tracking picture.
US-Israel-Iran War Latest Live News: US Military Considers Wider Smartphone Restrictions
The tracker shutdown also forms part of a wider effort by the US military to control the information generated by smartphones.
Reuters reported in July that some US troops deployed in the Middle East could be ordered to surrender their phones because of concerns that videos and other material posted online might reveal information about American bases.
Military officials face a difficult balance. Smartphones help personnel communicate and access information, but they can also generate digital information that becomes useful to an adversary.
The latest restrictions show that the military is increasingly treating device-generated data as part of the operational security environment.
US-Israel-Iran War Latest Live News: Why the Issue Matters During the Iran Conflict
The timing of the measures is significant because US forces remain involved in military operations linked to the conflict with Iran.
The Middle East deployment creates an environment where relatively small pieces of information can become operationally sensitive. A location signal, photograph, social-media post or application record could potentially provide clues about where troops or facilities are located.
That is why US lawmakers and military officials are examining not only government-controlled networks but also the wider commercial data ecosystem.
The concern is essentially about closing an information gap: preventing data generated for advertising purposes from becoming intelligence that could help an adversary.
US-Israel-Iran War Latest Live News: Pentagon Faces Pressure for Stronger Protection
The disabling of advertising IDs represents one step in the military’s effort to reduce digital exposure.
However, the latest disclosures also show why lawmakers believe the Pentagon needs to do more. Wyden and Harrigan want the department to determine whether existing safeguards adequately protect service members from commercially available location information.
The issue could also lead to broader restrictions on personal devices, applications and other technologies used by military personnel.
As the US military operates in active conflict zones, controlling digital footprints has become almost as important as protecting physical locations.
For American troops in the Middle East, the latest policy change sends a clear message: information generated by an ordinary phone can become a security concern when that phone belongs to someone operating on the battlefield.
