Israeli occupation forces use undercover agents to collect intelligence about Palestinians ahead of carrying out arrest campaigns and military operations or to secretly hunt Palestinian citizens throughout their places of residence.
Information about these forces is still secret, but leaks by former servants to mass media disclosed some information about them and about the techniques of their work.
There are several undercover units; each Israeli security service has one of these units. As these force wear and speak like Arabs, ahead of any Israeli operation, these forces mix with Arabs and take part in the operations. They give information, track individuals, kidnap or assassinate people.
During their training, they learn how to master the different accents of Arabic cities, villages and Bedouins and study the traditions of the different tribes.
Such units worked in the Gaza Strip during the first Intifada and helped undermining many attempts by Palestinian youth to carry out protests or throw stones. In the second Intifada, they undermined many attacks by armed Palestinian groups.
After Israeli disengagement from the Gaza Strip, they are now concentrated in the West Bank and East Jerusalem. They are spread in heavily populated areas among Arabs. However, they secretly carry out their missions, sometimes overtly. They can do it as they are armed almost all the time.
They work very hard with the Israeli Shabak and the Border Guards. Each person in these units undergoes 16 months of heavy and classified training, including guerrilla fighting and other developed fight techniques.
Analysts and experts in Israeli affairs insist that these units played the major role in decreasing the percentage of anti-Israeli operations inside Israeli cities.
Experts refer to individuals serving in these units "moveable military machines" and say that they sacrifice much of their personal life to carry on the "dual life scheme" to keep their missions successful.
