That seems to be urban myth ... my youngest son is a Radioman in Navy
EOD ... a special unit that's one notch below the SEALs ... NO Morse
training.

If they USE Morse at all, it would likely be sent and received by machine
as very high-speed bursts to send relatively short messages that would
be "low probability of detection" and very difficult to DF because the
bursts would be so short. (I don't know that they use this any more ...
it was available, but uncommon, back in 1990 when I left Rockwell-Collins
Defense Communications for the commercial sector. It's probably been
supplanted by FSK, since at equal symbol rates that has about a 9 dB
weak signal advantage over OOK Morse and it's actually simpler to
encode and decode in hardware/software.

I doubt that any of the radio comms the special forces use are
capable of Morse code.
