From this article on a special RFID tattoo ink:
The ink also could be used to track and rescue soldiers, Pydynowski said.
"It could help identify friends or foes, prevent friendly fire, and help save soldiers' lives," he said. "It's a very scary proposition when you're dealing with humans, but with military personnel, we're talking about saving soldiers' lives and it may be something worthwhile."
Excuse me? Did that person just imply that soldiers aren't human? I can't believe someone is considering tagging soldiers like livestock.

Elsewhere, apparently I'm not grateful enough. I suppose that's true; I'll have to work on that.
