I'm assuming they're still using the phone in some capacity in (what they thought) was offline mode. What they really need are phones with hardware switches for all radios, which of course almost don't even exist as a product. If a faraday bag worked for them they'd probably be better off just removing the battery altogether when they don't need the phone (removable batteries also aren't that common anymore).

It speaks to how terribly fit for purpose mobile devices are for soldiers in an active modern battlefield. Not only do they require discipline and technology training to prevent leaking positions, but most of them actually lack the capability to prevent leaking altogether no matter how trained you are.
