Not reporting to the service is prosecuted as an absence without leave or as desertion. The basic training takes place during the first eight weeks. At the end of the basic training, the actual training specialty and, consequently, the service time, are decided by the brigade commander on the recommendation of the company commander. Those ordered for leadership training attend next the NCO course. After the seven-week phase I of the course, a portion of the students are sent to Reserve Officer School or an equivalent institution for officer training, while the remaining NCO students complete the 12-week phase II of the NCO course. At the same time, the rank and file receive the specialized training of their branch, often at the same company as they underwent their basic training. After completion of their NCO or reserve officer training, the new conscript leaders are sent to normal units to serve as the leaders for the next incoming conscript cohort. The NCOs serve as corporals (in the Navy, petty officers 3rd class), with the possibility of promotion to sergeant (petty officer 2nd class). Those who have graduated Reserve Officer School or equivalent serve as officer candidates, ranking junior to career personnel but outranking conscript sergeants. At the end of their service, officer candidates are promoted to second lieutenants (in the navy, sublieutenants). Privates have a possibility of being promoted to lance corporal (in the navy, seaman) for extraordinarily good service. The service times are determined so that the conscript leaders are demobilized with the rank and file of that cohort. After discharge, the conscripts retain their ranks as inactive reserve ranks  After their military service, the former conscripts are placed in reserve until the age of 50 or 60, depending on their military rank. During their time in reserve, the reservists are liable for activation for five types of duty:  The males who do not belong to the reserve may only be activated in case of a full mobilization, and those rank-and-file personnel who have fulfilled 50 years of age only with a specific parliamentary decision. In addition to the mandatory refresher exercises, the reservist may be activated for voluntary exercises, but participation in these is, as name suggests, voluntary. However, when the reservist answers affirmatively to a voluntary activation request, he becomes an active member of the military for the duration of the exercise, with same rights and obligations as a mandatorily activated reservist, though with only an allowance corresponding only to the conscript's lowest allowance.
