BFT (Blue-force tracking) is going to revolutionize IFF. Because it
depends on geo-location knowledge, that's tough to spoof or jam.

Well, there's some nice claims about it, but it's still vulnerable to a
number of countermeasures. If you're rariating to tell someone that
you're who you are, you're also telling the bad guys "Hey! Come shoot
me!"

The same tech that makes a this useful for IFF makes it simpler to find
machines that radiate a lot.

Spoofing requires breaking encryption in real-time and jamming has to
be done continuously into multiple aperatures.

With increases in machines that *live* off of information flow, jamming
will suddenly become a lot more popular.

And with all of that extra RF floating around out there, radar-homing
missiles will be *very* much in vogue.
