The Pentagon Finally Admits That Location Data Is a Battlefield Problem


The Pentagon Finally Admits That Location Data Is a Battlefield Problem

The Pentagon confirmed adversaries are using commercial location data to track U.S. troops, exposing risks tied to smartphones and ad-tech networks.

For years, security researchers, privacy advocates, and intelligence analysts have been warning about the same thing: smartphone location data isn’t just an advertising product. It’s surveillance infrastructure that anyone with enough money can access.

Now the Pentagon is saying the quiet part out loud. According to a letter from U.S. Central Command obtained by Senator Ron Wyden and reported by Reuters, American military personnel deployed in active conflict zones have already been targeted using commercially available location data. Not hypothetically. Not as a future risk. It’s happening.

The disclosure matters because it marks the first known official acknowledgment that adversaries are using the commercial data ecosystem to track or surveil U.S. troops in theater. CENTCOM stated that it had received multiple reports involving hostile actors exploiting commercial location data against deployed personnel.

“In a letter shared with Reuters by U.S. Senator Ron Wyden, an Oregon Democrat
, opens new tab
, U.S. Central Command said it had “received multiple threat reports concerning adversary exploitation of commercial location data to target or surveil U.S. personnel in theater.”” reads the report published by Reuters.”The message, sent on April 14, offered no further specifics, but Centcom’s area of responsibility includes the Gulf, ​where U.S. forces are facing off against the Iranian military over the Strait of Hormuz.”

The details in the letter are revealing.

Asked whether military personnel are prohibited from carrying personal smartphones in theater, CENTCOM answered no. Instead, troops are instructed to limit geolocation exposure through operational security guidance and privacy controls. The problem is that even CENTCOM acknowledges those controls aren’t always enough.

“USCENTCOM’s geolocation risk guidance directs personnel to disable geolocationfunctionality when not needed; periodically review device and application privacy settings;and limit public sharing of information.” states the letter. “The guidance notes that disabling geolocationcapabilities does not always fully disable them on commercial products, requiringpersonnel to implement comprehensive device security measures including privacy settingreviews.”

That’s a polite government way of saying your phone may continue generating useful tracking data even after you think you’ve turned the right switches off.

The command also confirmed that adversaries are actively exploiting the commercial data market.

“USCENTCOM has received multiple threat reports concerningadversary exploitation of commercial location data to target or surveil US personnel in theater.” continues the letter. “The Threat Fusion Cell identified, tracked, and disseminated these threats throughthe USCENTCOM Threat Working Group and to component force protection personnel.Additionally, USCENTCOM has disseminated threat assessments to component forceprotection personnel demonstrating adversary capabilities to exploit commercial locationdata for targeting purposes.”

That sentence should probably have generated more headlines than it did.

Because the issue isn’t some advanced espionage capability reserved for intelligence agencies. The data often comes from ordinary apps, advertising networks, location brokers, and mobile tracking platforms that collect information from millions of devices every day. Once collected, it moves through a sprawling marketplace where buyers frequently have little visibility into who originally gathered it or where it eventually ends up.

Security researchers have warned about this for years. Back in 2018, Strava fitness data exposed sensitive military locations worldwide, as American and allied military personnel unknowingly shared exercise routes near bases in Afghanistan, Iraq, and Syria.

These maps clearly highlight otherwise hidden facilities and troop movements, creating serious security risks. Experts warn such data could help adversaries identify and target military sites, underscoring ongoing privacy issues with fitness trackers.

More recently, researchers demonstrated that commercially available datasets could identify military personnel, intelligence employees, and government contractors with alarming precision. The technology didn’t suddenly become more dangerous. People just kept ignoring the warnings.

Congress appears increasingly frustrated. In their letter to the Pentagon, lawmakers argued that commercial location data can reveal where troops gather, how they move, and what their daily patterns look like. That information can support surveillance operations, intelligence collection, drone targeting, missile attacks, or recruitment efforts by foreign intelligence services.

Government-issued devices reportedly have personalized advertising disabled through mobile device management controls. However, another advertising-related setting remains user configurable. CENTCOM says DISA is testing additional controls and is migrating devices to a new management platform that should allow location services to be fully disabled.

“the Personalized Advertising setting is disabled by group policy on theMobile Device Management Server.” states the letter. “However, Ad Targeting Information is not disabled andcan be edited by a user. DISA is currently testing implementation to disable the AdTargeting Information setting on government-issued cell phones. USCENTCOM is currentlymigrating government-issued mobile devices to a new Mobile Device Management Serverwhich will allow for location services to be completely disabled, estimated completiondate is 6 May 26.”

That effort is welcome. It also raises an uncomfortable question.

If intelligence agencies, lawmakers, privacy researchers, and military cyber units have been discussing this problem for nearly a decade, why are some of these protections only arriving now?

Part of the answer is that the surveillance economy grew faster than security policy.

Location data became so normalized that many organizations stopped treating it as sensitive intelligence. Yet for a deployed soldier, a contractor working near a military base, or an intelligence officer traveling overseas, a smartphone can quietly become a beacon broadcasting behavioral patterns to anyone willing to buy access.

No zero-day required. No spyware required. Just an ad-tech ecosystem that was never designed with operational security in mind.

Or as many security professionals have been saying for years: if an app is free, somebody is still paying for the data. Sometimes that somebody isn’t a marketer.

When it comes to content, there’s little I love more than a good, gritty crime drama. From their dark, cynical, often realistic portrayals of criminal underworlds, violence, and justice systems to their heavily flawed, obsessed, anti-hero protagonists and intense, gritty tones, it all sucks us in, and it’s why we can’t look away. These types of criminal shows have carved out a powerful space in television by refusing to glamorize the worlds they depict and being willing to confront uncomfortable truths.

This weekend on Amazon Prime Video in the U.S., we’re exploring three immensely popular, critically acclaimed criminal shows that will hook you from the get-go with their honesty, and my top pick is a must-see that reinvented the police procedural genre.

City on a Hill

A Wire-like look at corruption, race, and justice

Based on a story by Ben Affleck and author Charlie MacLean, the underrated crime drama City on a Hill revisits a charged moment in Massachusetts history known as The Boston Miracle. For 18 months in the mid-90s, gang-related violence dropped 63% as the result of a community-wide initiative developed in collaboration with the Boston Police Department, street workers, juvenile corrections officers, churches, and neighborhood programs. Kevin Bacon (Footloose), Aldis Hodge (Cross), and Jonathan Tucker (Kingdom) headline the cast.

Set in early 1990s Boston, corruption, violent criminals, and racism are normal parts of life, and to make matters worse, they’re backed by local law enforcement agencies. The series focuses on an unlikely alliance between hardened, corrupt, charismatic FBI agent Jackie Rohr (Bacon) and idealistic Assistant District Attorney Decourcy Ward (Hodge) as they work together to navigate the city and take down a family of armored car thieves, aiming to overhaul the broken criminal justice system.

Trivia challenge

From thrillers to tearjerkers — see how well you know these Amazon Prime Video films.

DramaThrillerTrue StoryComedySports

In Crime 101, what profession does the main character use as cover while pulling off elaborate heists?

That’s right! The protagonist poses as a real estate agent, using the job’s access and mobility as a convenient front for criminal activity. The film plays with how ordinary professions can mask extraordinary deception.

Not quite — the correct answer is real estate agent. The film uses this cover cleverly, showing how a respectable-seeming profession can provide the perfect camouflage for a career criminal operating in plain sight.

In Saltburn, which prestigious English university does protagonist Oliver Quick attend when he befriends Felix Catton?

Correct! Oliver and Felix meet at Oxford, where the stark class divide between scholarship student Oliver and the aristocratic Felix is immediately established. That university setting is crucial to the film’s themes of privilege and obsession.

Not quite — it’s Oxford where Oliver and Felix first cross paths. Director Emerald Fennell deliberately chose Oxford’s world of old money and social stratification to set up the film’s exploration of class envy and manipulation.

In The Tender Bar, based on J.R. Moehringer’s memoir, who plays Uncle Charlie, the bartender who becomes a father figure to young J.R.?

Spot on! Ben Affleck plays the warm and charismatic Uncle Charlie, earning considerable praise for the role. Affleck’s performance was seen as one of the film’s greatest strengths, bringing real depth to a man who shapes a fatherless boy’s entire worldview.

The correct answer is Ben Affleck. His portrayal of Uncle Charlie was widely praised as a career highlight, capturing the rough charm of a bartender who becomes the most important male role model in J.R.’s life.

In the 2024 Prime Video remake of Road House, who plays ex-UFC fighter Elwood Dalton, the new bouncer at a Florida Keys roadhouse?

That’s right! Jake Gyllenhaal steps into the role made famous by Patrick Swayze, playing a disgraced MMA fighter hired to clean up a rowdy bar in the Florida Keys. Gyllenhaal underwent intense physical training to prepare for the action-heavy role.

The correct answer is Jake Gyllenhaal. He took on the iconic role previously played by Patrick Swayze in the 1989 original, with the remake shifting the setting from Missouri to the Florida Keys and updating the protagonist’s fighting background to MMA.

Thirteen Lives depicts the dramatic 2018 rescue of a youth soccer team trapped in a cave in which country?

Correct! The film recreates the harrowing rescue of the Wild Boars youth soccer team from the Tham Luang cave in Thailand. The real-life operation captivated the world and involved expert cave divers from across the globe.

The answer is Thailand. The real rescue took place in the Tham Luang Nang Non cave in Chiang Rai province, where 12 boys and their coach were trapped for 18 days before a multinational team of divers managed to bring them all out safely.

In Manchester by the Sea, what unexpected event forces Lee Chandler to return to his hometown and become guardian of his teenage nephew?

That’s right! Lee’s brother Joe dies suddenly from congestive heart failure, pulling Lee back to a town filled with painful memories. Casey Affleck won the Academy Award for Best Actor for his portrayal of the grief-stricken, emotionally closed-off Lee.

Not quite — Lee returns because his brother Joe dies of congestive heart failure. The film, written and directed by Kenneth Lonergan, won two Academy Awards including Best Original Screenplay, and is celebrated for its unflinching portrayal of grief and guilt.

In American Fiction, what pen name does frustrated author Thelonious ‘Monk’ Ellison use when he writes a satirical novel pandering to racial stereotypes?

Correct! Monk writes his outrageous satirical manuscript under the pseudonym Stagg R. Leigh, a name that itself plays on stereotypes. The film, based on Percival Everett’s novel Erasure, won Cord Jefferson the Academy Award for Best Adapted Screenplay.

The pen name Monk uses is Stagg R. Leigh. The choice of pseudonym is itself part of the satire — a name loaded with cultural baggage. Jeffrey Wright received an Academy Award nomination for Best Actor for his nuanced portrayal of Monk.

In Air, the film about Nike signing Michael Jordan, which actress plays Jordan’s mother Deloris, who plays a pivotal role in negotiating his landmark deal?

That’s right! Viola Davis plays Deloris Jordan with commanding presence, portraying her as the savvy negotiator who helped secure the revolutionary contract that gave Michael unprecedented royalties. The real Deloris Jordan is widely credited with shaping the deal that changed sports marketing forever.

The correct answer is Viola Davis. She received widespread praise for capturing the intelligence and determination of Deloris Jordan, whose behind-the-scenes negotiations were instrumental in creating the Air Jordan brand that would go on to generate billions of dollars.

Thanks for playing!

Expect a thick atmosphere of 90s Boston authenticity, compelling power dynamics, character-driven narratives, and exceptional acting, particularly from Bacon, who gives a career-best performance. The show offers a serious, slow-burn exploration of one city’s criminal justice system while blending police corruption with family drama and social issues. Though fictionalized, it’s a fascinating look at Boston’s transition from a corrupt era to a new system and is executive produced by Affleck and Matt Damon.

River

A traditional “whodunit” investigation

Boasting a perfect critics’ score on Rotten Tomatoes, River is a six-part British police procedural and psychological crime drama about a haunted detective investigating his partner’s murder while also struggling with his mental health. Stellan Skarsgård (Good Will Hunting) and Nicola Walker (Unforgotten) star.

Detective Inspector John River (Skarsgård) is brilliant at what he does, but his fractured mind keeps him trapped between the living and the dead, haunted by “manifests,” or visions of murder victims, including his recently deceased partner, Stevie. Under enormous pressure from the media and psychiatric evaluation for his hallucinations, River works hard to navigate his guilt and, in the process, discovers the shocking truth about Stevie’s death.

Unlike typical crime shows, River focuses heavily on its protagonist’s mental states in the wake of his criminal experiences. The slow-burn, dramatic crime thriller is characterized by intense psychological scenes, a traditional “whodunit” investigation, and a masterful performance from Skarsgård. Expect a deeply human study of loss with smart writing, a genuinely creepy atmosphere, and a unique, emotional take on the police procedural drama.

The Shield

One of the best cop shows ever made

One of this century’s best crime dramas, The Shield is a multi-Golden Globe and Primetime Emmy Award winner. Michael Chiklis (The Commish), Walton Goggins (The White Lotus), Kenny Johnson (Ray), and Michael Jace (The Replacements) star alongside an enormous cast that includes Forest Whitaker, Katey Sagal, Kurt Sutter, CCH Pounder, Glenn Close, Benito Martinez, and more.

The hit FX show follows the corrupt activities of rogue cop Vic Mackey (Chiklis) in an experimental criminal division task force of the Los Angeles Police Department. He’ll go to any lengths to take down the criminals he and his team are chasing, including breaking the law and working with other criminals, and eventually he ropes his team into doing the same. Everything is set in a district rife with gang-related violence, drug trafficking, and prostitution.

Highly regarded for reinventing the police procedural and setting the standard for modern anti-hero dramas, the show paved the way for “prestige” television on basic cable with its raw, unflinching tone full of twists and thrills that explores the fine line between right and wrong. Over the course of 88 episodes, you’ll experience fast-paced action, moral ambiguity, high-stakes tension, and more riveting, gritty crime drama in one continuously solid storyline than you can stand. When viewing turns to obsession, don’t say I didn’t warn you. This one is a true gem.


Each of these hit criminal shows stands out for its realism and complexity, offering a much darker, thought-provoking take on crime storytelling that burrows into our brains and leaves us craving more. The platform has plenty of excellent crime dramas to choose from, so once you finish these three, stick around and see what else is there to transport you to the criminal underworld. Before you leave, though, be sure to check out everything coming to Prime Video in May 2026.
