U.S. Army Special Operations Combat Diver.?

I've recently watched the episode on "Surviving the Cut" about the Army's special operations combat divers and was wondering about them. Would anyone have any knowledge on these guys? I'm more or less curious on if they actually use their training? It's only that I've never heard of either Rangers or Green Berets using Combat Diving as an Insertion/Extraction technique in any conflict I've read about. So what I'm asking is have these guys possess the same skill set as SEALS or if I'm looking at Combat Diving should I even bother looking at the Army as an option? Thank you for reading.
