When it comes to survival there are two kinds. [a] where you want to survive long enough to be found, rescued, or walk out on your own. [b] avoid detection and capture as in special forces, rangers etc. When I think about survival I think about the former.
So the question on inquiring minds… why is so much gear setup for the later. If I’m trying to affect rescue I need reflective colors not camo. If I drop my gear in the dark I need to see it. If there is hunter near by I want him to see me and not shoot in my camp’s direction. Even hunters wear reflective vests with their camo jackets jumpers.
