The largest department of Mossad is Collections, tasked with many aspects of conducting espionage overseas. Employees in the Collections Department operate under a variety of covers, including diplomatic and unofficial. The Political Action and Liaison Department is responsible for working with allied foreign intelligence services, and nations that have no normal diplomatic relations with Israel. Additionally, Mossad has a Research Department, tasked with intelligence production, and a Technology Department concerned with the development of tools for Mossad activities.
Mossad was formed on December 13, 1949, as the Central Institute for Coordination at the recommendation of Prime Minister David Ben-Gurion to Reuven Shiloah. Ben Gurion wanted a central body to coordinate and improve cooperation between the existing security services—the army's intelligence department (AMAN), the Internal Security Service (Shin Bet), and the foreign office's "political department". In March 1951, it was reorganized and made a part of the prime minister's office, reporting directly to the prime minister.
Mossad's former motto, be-tachbūlōt ta`aseh lekhā milchāmāh (Hebrew: בתחבולות תעשה לך מלחמה) is a quote from the Bible (Proverbs 24:6): "For by wise guidance you can wage your war" (NRSV). The motto was later changed to another Proverbs passage: be-'éyn tachbūlōt yippol `ām; ū-teshū`āh be-rov yō'éts (Hebrew: באין תחבולות יפול עם, ותשועה ברוב יועץ, Proverbs 11:14). This is translated by NRSV as: "Where there is no guidance, a nation falls, but in an abundance of counselors there is safety."
Metsada is a unit responsible for attacking the enemy. Metsada runs "small units of combatants" whose missions include "assassinations and sabotage".
The Kidon is a unit which belongs to the Caesarea department (one of Mossad's eight departments). It is described by Yaakov Katz as "an elite group of expert assassins who operate under the Caesarea branch of the espionage organization. Not much is known about this mysterious unit, details of which are some of the most closely guarded secrets in the ." It recruits from "former soldiers from the elite IDF special force units." This unit has been a part of Israel's policy of assassinations, a policy that Israel has used more than any other country in the West, with Ronen Bergman stating it has carried out at least 2,700 assassination missions.
