I think SF commo men are still trained in code in case they have to transceive encrypted code over indigenous/expedient nets; or, monitor code transmissions. They didn't really use it after they went to burst devices back in the 1980s when the
KY-879/P Digital Message Device was issued (that's what my A-Team used). It was a special version of the
MA-4450 (MEROD), developed by Racal Communications Inc. in Salisbury, UK, for the US Special Forces.
Perhaps code could still be useful to auxiliaries and undergrounds in low intensity conflicts in some countries; but, it's no longer required for a ham radio license here and you can't WIRE PALADIN SAN FRANCISCO anymore.
