Edit request from Mtmsquared, 12 September 2011 

there are TWO wikipedia sites on the SAME TOPIC (special forces).

Both include similar info as the other,  but both  NEED A LOT OF WORK.

this site is the "most complete/factual" of the two (but still with errors):
http://en.wikipedia.org/wiki/Special_operations_force

this site is amazingly ridiculous in it's lack of complete facts:
http://en.wikipedia.org/wiki/Special_Operations

(how can you discuss "special forces" and not even include NAVY seals, the most
well known of the groups?)...

Just an FYI -  there are many other sites regarding  CIA and Special forces groups that are not linked, not fully explained, and missing facts.

I am in the military,  I do know what I'm talking about.   Wish I could help more, but this topic's disorganization on your website is far too messy for me to comprehend.

google the CIA website and it's description of special forces  (origins and current branches).    this may help you all

good luck.
