MD SAR GROUP

If you did want to explore the subject a bit more, I'd suggest MSAR's Intro to Search and Rescue videos, which are required watching for all team members: https://youtube.com/playlist?list=PL8m-rHyQsGdyEBO6re9_-VSaSAuLKbI8E or the ASRC's Essentials for Search and Rescue: http://www.asrc.net/pub/ASRC-Essentials-for-SAR.pdf. For anyone interested in an actual SAR textbook, I'd recommend NASAR's Fundamentals of Search and Rescue: https://www.amazon.com/Fundamentals-Search-Rescue-National-Association/dp/144964273X
