The conscripts first receive basic training, after which they are assigned to various units for special training. Privates who are trained for tasks not requiring special skills serve for 6 months. In technically demanding tasks, the time of service is 9, or in some cases, 12 months. Those selected for NCO (non-commissioned officer) or officer training serve 12 months.

second lieutenant, depending on their training and accomplishments. After their military service, the conscripts are placed in reserve until the end of their 50th or 60th living year, depending on their military rank. During their time in reserve, the reservists are liable to participate in military refresher exercises for a total of 40, 75 or 100 days, depending on their military rank. In addition, all reservists are liable for activation in a situation where the military threat against Finland has seriously increased, in full or partial mobilization or in a large-scale disaster or a virulent epidemic. The males who do not belong to the reserve may only be activated in case of full mobilization, and those rank-and-file personnel who have fulfilled 50 years of age only with a specific parliamentary decision.

. Soldiers of enlisted ranks with a limited contract (either 4, 8 or 12 years) or professional soldiers, who have filled their tour of duty, are likewise part of the reserve. This is also the case for women, but on the basis of the ''Soldatengesetz'' (Eng: ''Soldier Bill''), not the ''Wehrpflichtgesetz'' (''Conscription Bill''). Every soldier follows his rank with the initials "d.R." ("der Reserve"—"in the reserve"). So it does not affect whether the soldier is called up, placed in an inactive formation, or not. Only professional soldiers use the appellation "a.D." ("außer Dienst"—"out of service") after the end of their service. All others (part-time soldiers and conscripts) strictly use "d.R." until the end of their lives.
Reservists are an integral part of the Bundeswehr. They are essential for the capability of the armed forces in time of war.
Reservists can be active in the Bundeswehr in addition to their mandatory service. This mostly happens through (mostly voluntarily) military exercises or official events. Apart from that the Bundeswehr organises reservist unions as particularly representative supporting organisations of "voluntarily reservist work".
Eligibility for compulsory military service for soldiers and other servicemen of low rank ends at the end of the 45th year of age. Thereafter the conscript is no longer part of the reserve. Despite that the appellations "a.D." or "d.R." may still be used. Conscription for non-commissioned officers (NCOs) and officers lasts until the 60th year of age. Until the 32nd year of age every conscript is subject to military inspection.
Recognised conscientious objectors, who have completed their civil service, are nonetheless part of the reserve and in the event of war will be given a suitable non-combatant role outside the Bundeswehr, such as emergency medical services, clearing debris or minesweeping.
All conscripts who have not done their service belong to the ''Ersatzreserve'' (replacement reserve).
Israel

After personnel complete their regular service, the
IDF may call up men for:
* reserve service of up to one month annually, until the age of 40–45 (reservists may volunteer after this age)
* active duty immediately in times of crisis
In most cases, the reserve duty is carried out in the same unit for years, in many cases the same unit as the active service and by the same people. Many soldiers who have served together in active service continue to meet in reserve duty for years after their discharge, causing reserve duty to become a strong

experience in Israeli society.
Although still available for call-up in times of crisis, most Israeli men, and virtually all women, do not actually perform reserve service in any given year. Units do not always call up all of their reservists every year, and a variety of exemptions are available if called for regular reserve service. Virtually no exemptions exist for reservists called up in a time of crisis, but experience has shown that in such cases (most recently, the 2006 Lebanon War) exemptions are rarely requested or exercised; units generally achieve recruitment rates above those considered fully manned.

conscript completes his active service, he attains the status of being an "operationally ready" citizen-soldier, and is thereafter known as an Operationally-Ready National Serviceman (NSman). NSmen are the equivalent of other militaries' reservists. The slight difference in nomenclature is as to these NSmen will form the main fighting personnel of the Singapore Armed Forces upon wartime or any national exigencies. In practice, Operationally-Ready NSmen of all the tri-service (SAF, SPF and SCDF) are all routinely called up annually for reservist duty until they complete their reservist cycle obligations or upon the legally statutory discharge age of 40 for Warrant Officers, Specialists and Enlistees ( WOSEs) and 50 for Officers.
