Finland
The rank ''vänrikki'' is used in active service by reserve officers who remain in service as for 6-to-12-months-long volunteer contract period. In addition, it is the lowest reserve officer rank.Conscript officer
The rank has been mainly a reserve rank. The future conscript officers are selected from the whole pool of conscripts. After a basic training of two months, a portion of the conscripts are selected for NCO training. After 2 months of NCO training, the most suitable are selected for reserve officer training and promoted to officer students. The 3½-month-long reserve officers training usually takes place in the Reserve Officer School, and afterwards, the candidates are promoted to officer cadets (). They serve the remaining 5½ months of their conscription practicing as platoon commanders as well as training other conscripts. Finally, successful officer cadets are discharged with the rank of ''vänrikki''. In the reserve, reserve officers may be promoted up to majuri (Major), although there have been extraordinarily promotions to everstiluutnantti (Lieutenant Colonel). The Navy equivalent rank is ''aliluutnantti'' ( Sub-Lieutenant). If mobilization is effected, officers in the reserve fill most junior officer duties of the war-time Finnish army. Especially, most platoon and company commander positions and junior staff officer duties are filled with reservists.Professional officer
The National Defence College accepts both reserve officers and reserve NCOs. Those cadets who did not receive reserve officer training during their conscription are usually promoted to the personal rank of ''vänrikki'' during their studies. However, upon graduation, professional officers are promoted to luutnantti. During the early 21st century, the National Defence College also had a one-year program to commission professional officers with the rank of ''vänrikki'' and a fixed service term of five years. The rank is the lowest commissioned officer rank. Formerly a school called ''Maanpuolustusopisto'' (MpO) had ''vänrikki'' as the rank given to new graduates. These officers were known as ''opistoupseeri'' (usually translated "Warrant Officer"), and could be promoted up to '' yliluutnantti'', senior lieutenant, (company vice-commander), and later, to ''kapteeni'' (company commander). The ''opisto'' level ceased to exist in Finland (other schools were redefined asExtraordinary
Simo Häyhä, believed to have the highest number of sniper kills in any major war, was extraordinarily promoted to ''vänrikki'', from alikersantti (Corporal), personally by Marshal Gustaf Mannerheim.See also
