Military mail, as opposed to civilian mail, refers to the postal services provided by armed forces, that allow serving members to send and receive mail.
Military mail systems are often subsidized to ensure that military mail does not cost the sender any more than normal domestic mail traffic. In some cases, military personnel in a combat zone may post letters and/or packages to the home country for free.
