4. Israeli Shayetet 13 This Special Ops group shares the Israeli Army motto: “Never Again”, referring to the Holocaust.
Though they are one of three special units, the Shayetet 13 bears the closest resemblance to the US Army's Delta Force. They are specially trained for rescuing hostages and in counter-terrorism.
Though they remain an extremely secretive group, the most public noted mission was Operation Spring of Youth.
During this operation, the Shayetet 13 went into Beirut Lebanon where they hunted down and killed all the terrorists involved in the 1972 Munich massacre of 11 Israeli athletes.
