I'm sure special forces are incredibly tough and very skilled - I was just wondering whether there would be any reason for them to train in the skills relevant to cave diving.

Wreck salvage. It's not quite the same skillset as cave diving, but wrecks have many very similar hazards.

Of course, the most dangerous person is someone who thinks they know what they are doing.
