Ghurkas are the third-world equivalent to SEALS -- or, actually, more likely -- Special Forces.
Nepal, whether is a Third World Country or not is not the issue. However, it is world known that the Gurkha's are the absolute killing machines bar none.
Nepal takes great pride in advertising the Gurkha's based on it's History as the Ultimate Warriors trained in all aspects of War Combat.
A particular of Gurkha's is that they do not take prisoners (like the Yugoslav's in WW II).
When they are done, everybody is toast.
Great Britain has a division of them.
I do not wish anyone to be there and meet them fellows under war conditions.
