I think that the idea of privacy is wishful thinking if the people in these locations are allowed to have their own unvetted electronics. It would not take more than one trojan smartphone application with a social media login until you are able to identify the person (and maybe graph more out of that, no GPS needed!).

And as an anecdote, back during my conscription, we were told to disable location services altogether and not take photos during training sessions, but I honestly think it had more to do with keeping in mind the best practices rather than avoiding anything to get "leaked". The officers were sometimes seen with phones of their own, meaning the government issued tinfoil ones.
