According to Constitution of the Islamic Republic of Iran all men from 18 years old or older must go for military service or conscription (Persian: سربازی read "Sarbâzi") in the Armed Forces of the Islamic Republic of Iran. The length of conscription is between 18 months to 2 years.
History
Conscription was first introduced by Reza Shah in June 1925 and approved as law by the National Consultative Assembly. At that time every male person who had reached 21 years old must serve for military for 2 years. However, as the country needed 100,000 men and the qualified population then was 1,000,000, they announced just one man between every 10 men must serve in the military.
