Federal officials announced this week that several branches of the U.S. military have turned off advertising identifiers—commonly known as MAIDs—on government‑issued phones and computers. The move follows multiple threat reports indicating that foreign adversaries could purchase commercially available location data to track or target American personnel deployed in the Middle East.
Why the change matters for service members
Advertising identifiers are unique numbers attached to a device that allow ad networks to follow a user’s activity across apps and measure ad effectiveness. When combined with location information, those identifiers can reveal a device’s movements, potentially exposing a soldier’s “pattern of life.” Data brokers collect and resell such information, meaning an adversary could obtain sensitive location records without hacking a military network.
Disabling the identifiers interrupts one avenue of tracking, though it does not render a device completely invisible. Other technical data, network signatures and location permissions can still be used to follow a device. Nonetheless, the Pentagon’s action represents a concrete step toward protecting the privacy of troops.
Branch‑by‑branch rollout
The Air Force told Sen. Ron Wyden (D‑OR) that it disabled advertising identifiers on its computers and mobile phones roughly two months ago. U.S. Special Operations Command reported that it recently turned off the identifiers on its Windows devices. The Army confirmed that advertising identifiers on Army‑managed mobile devices have been disabled since early 2026, and that Windows computers have been blocked from using them since before 2021. The Navy added that it disables mobile advertising identifiers within its secure application environment on government‑furnished equipment.
Congressional pressure and bipartisan support
The changes come after months of pressure from lawmakers concerned about the security implications of commercially traded data. In April, U.S. Central Command warned Congress that it had received “multiple threat reports” about adversaries using commercial location data to surveil U.S. personnel during Operation Epic Fury. A bipartisan letter in May, signed by 14 members of Congress—including Republican Reps. Keith Self and Michael Cloud—called for stronger safeguards.
Sen. Wyden and Rep. Pat Harrigan (R‑NC) sent a follow‑up letter Friday urging the Pentagon to assess whether the current measures fully address the danger. Harrigan warned that “adversaries should not be able to pull out a credit card and buy information that helps them track American troops.” Wyden noted that the military’s efforts “have not been effective at neutralizing this threat,” prompting the Pentagon to promise a direct response.
Agency recommendations and civilian relevance
Both the National Security Agency and the Cybersecurity and Infrastructure Security Agency have recommended disabling advertising identifiers, reinforcing the Pentagon’s decision. The same identifiers are used on civilian smartphones, meaning the guidance also applies to the public. Google advises Android users to delete their advertising ID via Settings → Privacy → Ads, while Apple directs iPhone users to Settings → Privacy & Security → Tracking to manage app permissions.
Although these steps improve privacy, they do not eliminate all forms of digital tracking. Applications with separate location permissions can still gather location data, underscoring the need for continued vigilance by both the military and everyday users.
Looking ahead
The Pentagon’s action reflects a broader effort to safeguard the personal data of service members against foreign exploitation. As technology evolves, further measures may be required to stay ahead of adversaries seeking to leverage commercial data streams for intelligence purposes.
