Any piece of technology with remote access is hackable and a poor piece of equipment for serious conflict. It is already well known every cell phone signal in a conflict zone can be intercepted and monitored and the location of thesignal pinpointed.
Hand held radios or anything emiting a strong enough signal to be seen gives away the location of the user.
Imagine an AWACs seeing the location and what the rifle is pointing at of anyone using this technology for miles in all directions. Or even just locating the cell phone location of anyone using the application and turning cell phone towers into weapons against the enemy. Would make it easy to know where to send the drone to bomb or tactical unit to raid wouldn't it?
If you cannot physically turn off all radios on a device, not just in software, it is poor technology for serious use. If it requires remote connection to even access features it is even worse.
Being electronic already makes such things highly vulnerable to EMP, jammers, and other electronic countermeasures, nevermind nuclear generated EMPs.
One day professional soldiers will be facing forces exploiting these same vulnerabilities in their own equipment. If you emit a signal all the time you are easily pinpointed and as good as dead. You won't sneak up on anything and the bomb/artillery knows where to go.
Cell phones are probably the greatest weapon the police state has ever had. Imagine everyone willingly bugging themselves with microphones, one or more cameras, and a constantly updating location. Back in Cold War times a lot of effort went into even getting microphones into a location, now everyone brings microphones, cameras, motion sensors, and other sensors just about everywhere for you.
With full lists of those it communicates with, and AI to analyze what eash user does and create a profile of them for review. Google is the biggest cell phone operating system provider with Android, keeping track of all of that and selling and making available the data on most people just as face book does to generate most of its revenue. (This website with google ads even keeps track of every user that visits it. So the cell phone/computer informs them of where data is being sent, and google ads informs them from the other direction of what is coming and from where. Google knows all and thats without even going into nodes and other things in between they have access to or control.)
Tying any piece of military or arms related hardware to cell phone use just makes it extremely vulnerable.
