In my defense, a laser powerful enough to punch a hole through a sheet of metal and can be handheld is already in existence, and, the main constraint, power supply, [url]https://en.wikipedia.org/wiki/Lithium%E2%80%93air_battery[/url] is being overcome incredibly quickly. And solar powered flashlights exist, they even come with battery's. Hell, I have one on my table right next to me. [url]http://www.goalzero.com/p/239/torch-250-flashlight[/url]
I mean, if we have functional cryonics, I must imagine that we would be able to make a functional handheld laser pistol. (or rifle) And if the cryonics is done through nanotech, can I also have a nanocolony that can act as a first aid medic kit? I'm making my character to be military, so it would make sense that she would have this stuff and know how to use it.
