9. Shayetet 13
Country: Israel
Branch: Israeli Navy
Motto: n/a
Shayetet 13’s most notable achievement is the elimination of all members of the terrorist group responsible for the 1972 Munich Olympics massacre, which saw 11 Israeli athletes dead. In an operation aptly named the Wrath of God, Shayetet 13 operators, together with other Israeli special forces, executed a raid on Lebanon and killed several members of Black September terrorist group. That level of badassery is sure to secure them a spot on the list of best, most elite hardest training special forces in the world.
