It all depends on which branch of service you are in. But, technically, the DOD has always called it what I called it.

That manual really has some great info in it; shelters, how to test plants for edibility, using plants as medicine the list goes on. It is the ultimate survivors guide, but isn't really designed to be used alone. It is supposed to be part of the course, which isn't fun. I still think it is better than any survivor how to book I have read.
