No cell phones on the battlefield seems like operational security 101. Deployed soldiers should not get cell phones, ever. I wonder if this happens more because of bad military policy about cell phones, bad enforcement of said policy, or because even for deployed soldiers it's next to impossible to survive in the modern world without a cell phone. I suspect it has a lot to do with the latter. Cell phones are completely inescapable.
