Although still available for call-up in times of crisis, most Israeli men, and virtually all women, do not actually perform reserve service in any given year. Units do not always call up all of their reservists every year, and a variety of exemptions are available if called for regular reserve service. Virtually no exemptions exist for reservists called up in a time of crisis, but experience has shown that in such cases (most recently, the 2006 Lebanon War) exemptions are rarely requested or exercised; units generally achieve recruitment rates above those considered fully manned.
