DARPA is looking to modify red blood cells with either natural or synthetic "cargoes" to aid warfighters' abilities in dangerous and extreme environments.
One time, I was trying to motivate a retired marine friend of mine who was being lazy by saying “on your feet, soldier!” as a reference to Terminator, myself being ignorant of the difference.
What if they’re marines? Have you ever tried calling a marine a soldier to their face? I don’t recommend it.
In my experience “soldier” is fine. Just don’t call a Marine a Sailor.
But they’d love to tell you about their favorite flavor of crayon!
I’ve seen them get pissy and at least correct people over either, but YMMV I guess

Credit where it’s due: it got him on his feet.
