special ops groups wich is the best most powerful?

im not sure if i posted in the right catagory

i know navy seals, green barrets but is there a group that that encompasses all the major elements of the military like a super secret special forces group that includes a special forces space unit/navy seals

what are the top group and are there any most people arent aware of?

1.navy seals
2.green barrets
3 swat


space-ufo retreval; team and what are their names and specialties does anyone have a list?

what im trying to say is is there a bran that supersedes all the the major branches of the military - that bypasses them

most of you will say yea the mib black helicopter etc. but to to they a a name or a compartmentalized name?

The number one is the Australian S.A.S.(Special Air Service)

They were the first to be sent into Kuwait, prior to the commencement of Operation Desert Storm.
In Vietnam, they had 3 only casualties in the whole conflict, and as my old man recounts to me, the N.V.A. were terrified of them above and beyond any of the other forces there.
