The SAS, IMO.
The Jägerkorps, KSK9 US Navy SEALS rank right up there with them though..
Here is the difference - the USMC is starting to push 190,000 strong. We're regular forces... and I'll offer we very well may be the best trained force that is that large and is capable of fulfilling such a broad range of missions and objectives.
Of course spec ops type units such as SEALS are better trained at what they do.
Nobody has the intimate knowledge of training throughout all different units, and it is a very difficult thing to compare - and often leads to chest pounding.
