Israel has a large force of commando troops for a country its size. There are two small battalions of Arabic speaking troops used for undercover operations and raids into the Occupied (Palestinian) territories). Sayeret Shimshon (Unit 367) is assigned to the Gaza Strip, while Sayeret Duvdevan (Unit 217) takes care of the West Bank. There are four companies of Ranger type troops (Palsar) that normally each support one of the four elite infantry brigades of the army, and two more to support armored brigades.. There are also three LRRP companies (Special Command Teams), with one assigned to each of the army's corps headquarters. Lotar Eilat and Unit Yamam are two hostage rescue units (each under 100 troops.) These units are also used as commandos (as when there is a lot of violence with the Palestinians.) There are also several hundred highly trained LRRP troops assigned directly to intelligence units. The navy has a SEAL unit (Shayetet 13) of about 400 men. This unit is more selective than the other commando units, with about 80 percent of it's candidates failing the training course, compared to about 50 percent with other units. The navy also has a company size unit of divers (similar to U.S. UDT). The police force also has over a thousand specially trained men who are a cut above your usual SWAT teams.
