Have read lots on MACVSOG Vietnam stuff years ago. They did what they had to and that many survived is amazing. We owe them all so much beyond gratitude.
SOG was crazy enough to survive. Kind of like the Jarhead Force Recon. Never worked with SOG, but did so with Force Recon. Only group of maniacs I ever met that called friendly fire on their own position and lived to joke about it. If I ever need to go completely insane I will follow their path.
