Is there a list of all the types of Special Forces?

Meaning, I know about the SEALS, Rangers, Delta, HALO, Air Force ParaRescue for the US Military etc…
I also have heard there are at least thirty more most civilians have never heard of. Is there a itemized list anywhere showing just exactly how many there actually are, their names and what they do?

Yes, but if I showed it to you, I’d have to kill you.

lol

The wikipedia article here:
http://en.wikipedia.org/wiki/United_States_Special_Operations_Forces
seems to have… somewhere between 15 and 30 US special forces listed, depending on how you count this stuff.
