Pentagon restricts use of fitness trackers, other electronic devices that reveal locations

U.S. military troops and other defense personnel at sensitive bases or certain high-risk war zone areas won’t be allowed to use features on fitness trackers or cellphone applications that can reveal their location, according to a new Pentagon order.

The memo stops short of banning the devices, which are often linked to cellphone apps or smart watches and can share users’ GPS locations and exercise details to social media. But it says the “geolocation capabilities” can present a “significant risk” to military personnel, so those functions must be turned off in certain operational areas.

Under the new order, military leaders will be able to determine whether troops under their command can use the GPS function on their devices, based on the security threat in that area or on that base.

“The rapidly evolving market of devices, applications, and services with geolocation capabilities (e.g., fitness trackers, smartphones, tablets, smartwatches, and related software applications) presents significant risk to Department of Defense (DoD) personnel both on and off duty, and to our military operations globally,” the order says.

It adds, “These geolocation capabilities can expose personal information, locations, routines, and numbers of DoD personnel, and potentially create unintended security consequences and increased risk to the joint force and mission.”

Defense personnel who aren’t in sensitive areas will be able to use GPS applications if their commanders conclude it doesn’t pose a risk. For example, troops exercising at major military bases around the country, such at Fort Hood in Texas or Norfolk Naval Station in Virginia, would likely be able to use the location software on their phones or fitness devices. Troops on missions in more sensitive locations, such as Syria, Iraq, Afghanistan or parts of Africa, meanwhile, would be restricted from using the devices or be required to turn off any location function.

Concerns about exercise trackers and other electronic devices made headlines in January in the wake of revelations that an interactive, online map was pinpointing troop locations, bases and other sensitive areas around the world. The Global Heat Map, published by the Strava fitness app, used satellite information to map the locations of subscribers to Strava’s fitness tracking service. 

At the time, the map showed activity from 2015 through September 2017. And while heavily populated areas were well lit, war zones such as Iraq and Syria showed scattered pockets of activity that could denote military or government personnel using fitness trackers as they move around.
