I personally recommend the SAS Survival Handbook, Third Edition: The Ultimate Guide to Surviving Anywhere Paperback – November 11, 2014 by John ‘Lofty’ Wiseman which can be found on AMAZON here.
I bought several copies of this book for family and friends last year. It is a bit of overkill but as someone who has been through military survival courses I can tell you that even this old dog learned a trick or two from this book. Well worth the $14.00. — OOV
