When you’re out in the desert or on a glacier, you’ve got to treat the wound before it becomes a second infection. First thing is clean, then pack it tight, keep it off the line of fire, and move it to a safe spot. We never rely on fancy gadgets – we rely on what we know works and what we can carry. A portable light therapy kit could help if you’ve got the power source and the right wavelength. It can speed up tissue repair, but only if you’re using it after the wound’s been sealed and the patient is stable. In training, I make sure everyone knows basic first aid, how to improvise dressings, and when to send a wounded teammate back to base. Add a light kit to that list, but don’t let it replace solid field skills. It’s a useful tool, but it’s only as good as the training that comes with it.

That’s the mindset we need. Keep the science tight, but always test it in the field before you trust it. Basics first, tech second.
