An IDF reservist is an Israeli citizen who has completed their mandatory military service and is now part of the IDF Reserves. They can be called back to active duty in times of need, such as during times of conflict, war, or other national emergencies. All Israeli citizens over the age of 18, regardless of gender or ethnicity, are obligated to serve in the military during wartime. However, only those who completed at least 20 days of reserve service in the past three years are considered to be active reservists). Women in non-combat positions are released from this obligation upon the birth of their first child). Reserve duty in Israel can vary in terms of the duration and frequency of service, and reservists are required to participate in refresher training exercises to ensure they remain capable and up to date with the latest military tactics and equipment. The IDF calls its reservists for duty through a special call-up letter containing details of the reserve duty they are obliged to undertake, including the relevant dates and location).
