I think that a spread spectrum burst type transmission can be
intercepted and given a rough bearing. The money to do this is
miniscule in comparison with making Trident missiles into hand
grenades.

The command post does not move between transmissions. Spread
spectrum/frequency hopping systems return to previous frequencies every
few seconds. Just use several bursts to home in on the transmitter.
?? You transmit only when you want to issue new command to the swarm,
not to control every little thing. You can have minutes without
transmission, then 10ms transmission, followed by another long silence.

And you can also have plenty of cheap decoy trasmitters, just to make
it easier to intercept ... something. ;-)
