I am pretty sure the Army would find a way to UCMJ me if I did not have a cellphone. I like to connect with my troops whenever I need to. The flip side is the command micromanagement 24/7 is haunting some days. What ever happened to formations?
I sincerely will enjoy a day when I no longer have a phone to worry about ringing and it not be family or some legit emergency.
I agree with Dusty about its good to have comms. When I get to the point I can, I think I will go the "emergency phone" route and just not give out the number to anyone.
