Jash (Kurdish: Caş or Cahş, literally meaning "donkey's foal"), or fursan is a type of collaborator, usually a military unit composed of people of Kurdish descent that cooperates with enemy combatants against the Kurdish army, Kurdish rebels, or the Kurdish civilian population. The term is considered derogatory in a cultural sense in much the same way as quisling is.
During al-Anfal campaign, the military campaign of extermination and looting commanded by Ali Hassan al-Majid, his orders informed jash units that taking cattle, sheep, goats, money, weapons and even Kurdish women was legal.
In the latter half of the 20th century, Kurds who became collaborators with the Iraqi government have been referred to as jash. The number of jash increased to "as many as 150,000 by 1986" as a method of avoiding military participation in the Iran–Iraq War. These jash then realigned with the rest of the Kurdish people during the 1991 Kurdish uprising. It has been stated by a number of Kurds that "the jash had been completely forgiven".
