Guns are kinda necessary.  GPS?  Useful, but if they don't have coverage 
for some reason, it's not a deal killer.  After all, having a map also is 
useful, or having local knowledge of the area.

That's not what you said, though, you said it *needs* GPS to exist.  It 
doesn't need it, it's just a very useful tool so they know where they are 
without resorting to other methods.
