These things need to include more details. What is the report that ads were used to target deployed troops? What is the device use policy as of today? FOBs and semi-permanent installations are not secret locations. They're extremely obvious, have marked fences, gates, and guards in uniform. They're on satellite and aerial photos, sometimes on maps, depending on how long they've been in place. During patrols and any other movements in which unit locations are meant to be secret, as of 15 years ago when I was still serving, phones or any other kind of personal electronic device were not allowed. Even in training exercises, as far back as 2009 that I experienced, and probably further back than that, SIGINT units used radio triangulation to find and kill you when you used a phone during an exercise, which resulted in both removal from the exercise and reprimand because you weren't supposed to have a phone with you in the first place. They also captured and publicly shamed shit like getting nudes from your girlfriend or even just exchanging text messages.
If deployed personnel are sharing videos of their deployment activities to social media, how is that allowed? It can't be, right? They're violating some policy in doing that. Unit commanders have your social media accounts and monitor what you do there. Uniformed servicemembers have never had any expectation of privacy. UCMJ doesn't have 4th amendment rights. Your room, housing, belongings, car, phone, can all be searched with impunity at any time, with or without notice. All communications can and will be intercepted and read.
