The 9 deadliest special forces in the world

Elite special forces are some of the best-trained and most formidable units a country can boast.

They go where other soldiers fear to tread, scoping out potential threats, taking out strategic targets, and conducting daring rescue missions.

These really are the best of the best.

Although it's extremely difficult to rank these forces relative to one another, there are some units that rise above the rest in their track record and the fear they instill in their adversaries. These soldiers have been through rigorous training exercises designed to weed out those who can't hit their exacting standards.

In a world where the importance of the sheer size of a country's military forces is no longer a guide to their effectiveness, these soldiers are the ones states look to in order to get the job done.
