Shows how different military minds are from other professions. When I saw "in the field," I'm a geology student so I assumed it would be scientists out in the middle of nowhere with these things. But I guess the military would be very similar aside from *slightly* stricter rules from an employer.
I've got to take a class that is six weeks of field work next summer, and I was a little torn on whether I would take it or not. After figuring out the whole step tracking, heart rate monitoring, exercise, etc., I definitely think I'll take it with me. I want those rings to light the heck up. Maybe there will even be some useful geology apps by then, even if it's as simple as some sort of map. It's definitely easier to tell time.
In the near future, I wouldn't be shocked if the military developed its own type of smartwatch to issue to troops. I know you guys have coms, but if these were modified to send the health data back to a central command center, commanders there might get a better sense of if the unit is sensing danger or struggling to maneuver through a terrain. Think of it kind of like how astronauts have a lot of medical hookups on them. If a watch could monitor all of what NASA checks now, it could probably help make astronauts more comfortable. Only problem with that would be the completely useless accelerometer.
I also wonder if these watches or any other device could be used to make all sorts of weapons useless if stolen by enemies. I know ISIS stole a lot of weapons from Iraqi fighters who were either defeated or fled over there. There's obviously an issue with glitches making the weapon unusable for the good guy intended to use it, but maybe that can be overcome somehow.
