Conscription is enshrined in art. 51 of the 1994 Constitution, which states: "The defence of the Republic of Uzbekistan is the duty of every citizen of the Republic of Uzbekistan. All citizens are obliged to perform military service or alternative service in the way as detailed in law."
Its legal basis is the 1992 Law on Defence. 
All men between the ages of 18 and 27 are liable for military service.
