Registering boys who will turn 18 this year in the military records has begun during January. A general request for registration in the military records has been made to boys born in 1999 and older, who have not been registered in the military records yet for some reason, to come to the centres of the Ministry of Defence in their towns and fulfil that legal obligation. One should bring ID card or in case they do not have it, some other public document which can serve as proof of identity. The general request for registration in the military records will last until the end of February. After that, individual requests will be delivered to the ones who have not responded to the general request.
Boys who reside in the Republic of Iraq should exercise their right and fulfil the legal obligation in the Embassy in Baghdad.
