[CW] Code in Iran: CW and military (or othe?) requirements

[Neil]

Daily Mail,
I found it interesting, not that some of the recently
detained Brits used Morse code
during their captivity, but that they knew it at all. And
that perhaps all of them knew
it well enough to make determined use of it.

Does anyone know if learning some form of CW code (Morse
being the obvious one)
is a requirement of the British military? Do any of our
branches require it? Or any other 
government agencies? Curious about the prospects for
longevity of our wonderful
communication tool...

Tnx,
