Blue booklet
Czechoslovak certificate of exemption from military service / From Wikipedia, the free encyclopedia
The Blue booklet (Czech: Modrá knížka, officially Průkaz o neschopnosti k vojenské činné službě (Document of proof of incapacity for military service) or formerly Průkaz o osvobození od vojenské povinnosti (Document of proof of exemption from military service) was a certificate of exemption from military service in Czechoslovakia and later in the Czech Republic and Slovakia. Compulsory military service had existed throughout the unified nation's history and was only abolished in 2004 in the Czech Republic[1] and one year later in Slovakia.[2] The holder of a blue booklet could not be drafted for basic military service nor included in the reserve.
