"anyone define "best" yet "
Who won the olympics?
Usually they go by medal count, then you get arguments over why a bronze and gold count both as 1 medal...
"Hmm, to consider what force would be best, you'd have to ask what at. They aren't front-line soldiers, or they wouldn't be 'special'. So like people said if you want hostage rescue you have to specify. Otherwise Spetzsnaz would probably be the best, with the the widest scope, the most official support, consistent funding, an expansive array of capabilities, and all that. They might not be the best at any one thing, but they wouldn't be worse than #2, and there's likely no-where else that covers all the things they can do."
