Interesting topic, the best kind of survival training in my view is experience over time, when I'm hunting I also look for identifiable plants for eating, do a spot of fishing using different methods, the majority of the time I sleep out in the bush (I don't like huts) I'm a big fan of survival training, I've read a number of good books over the years and take my favourite methods for traps etc and head out in the bush and try them.
