  military service is service by an individual or group in an army or other militia, whether as a chosen job or as a result of an involuntary draft (conscription). some nations (e.g., mexico) require a specific amount of military service from every citizen (except for special cases, such as physical or mental disorders or religious beliefs). a nation with a fully volunteer military does not normally require mandatory military service from its citizens, unless it is faced with a recruitment crisis during a time of war. thumb|right|500px|     thumb|timetable of military duties, switzerland. ==summary of countries== in this summary, 195 countries are included.office of the united nations high commissioner for human rights, geneva, switzerland, 1997, via nationmaster: http://www.nationmaster.com/graph/mil_con-military-conscriptionthe cia world fact book â military service age and obligation. https://www.cia.gov/library/publications/the-world-factbook/fields/2024.htmlj. jih. dual nationality, conscription and death penalty. http://web.archive.org/web/20091027100908/http://geocities.com/jusjih/dncdp.htmlØ³Ø±Ø¨Ø§Ø²Û Ø¯Ø§ÙØ·ÙØ¨Ø§ÙÙ Ø¢Ø±ÙØ Ø§Ø¬Ø¨Ø§Ø±Ù ÙÙ ===no defence forces===  the following nineteen countries have been identified as having no defence forces or as having no standing army but having very limited military forces:   * * * * ** ** * * * **  ** * * ** * * * ** *  : ===no enforced conscription===  the following 105 countries have been identified as having no enforced conscription:   * * * * * * * * * * * * *{{flag|bosnia and herzegovi
