SF troops used to be issued a small black vinyl 6 ring binder notebook they were given from Frankfurt Arsenal that gave IED instructions. Sneakypete might have seen that text in his career..... There "is" only one commercial IED 101 book on the market that is an exact copy of that SF text but I won't spill the beans in an open forum.
One just has to look at old Kurt to understand this guy was clearly self taught through the trial and error method.
Stay Safe Coop !
