It would seem that many people think the SAS is the best because of their high profile. This simply isn't true. Many special forces around the world
undergo just as rigorous training and in some cases more so.
The Australian SAS would have to be the best multipurpose special forces unit in the world. They are capable of filling the roles of both the Brit SAS
and SBS or similarly the roles of Delta and SEALS.
They have also seen almost constant combat since the 1950's, many of their missions still being secret. They are also better funded than the Brirish
All you have to do is look at their history in Vietnam a 500-1 kill ratio.
The Brit SAS maybe good but as far as being the best, this is just a fallacy. This is because it seems that every ex SAS trooper seems to write a
book, telling everyone how good they are.
Delta would kick the Brit SAS's arse in close quarters battle, no doubt about it. Many SAS guys agree with this statement.
