If I understand you correctly, your target audience for this product already has a firm base of fundamental survival skills and you want to build on that with urban and modern technology, yes?
The problem with urban operations and exploiting technology, unlike old school survival, much of it is NOT labeled for public consumption...at least considered FOUO (for offical use only).
With that, a lot of folks in the know can't answer your call with all of the good info you're asking for.
