Having a flashlight as useful as this is pretty cool, often what the tools that are useful for the military end up having handy civilian applications as well. The ability to control light intensity through pressure is novel, at least to me, but this seems like it makes it a lot easier to quickly and quietly adjust light brightness as opposed to somewhat obnoxious button flipping. An auto SOS is handy as well, it's also annoying to manually do that I imagine.
