Everstiluutnantti (Lieutenant colonel, Swedish: Överstelöjtnant[1]) is an officer's rank in Finland, immediately above Majuri (Major) and below Eversti (Colonel).
During peacetime, an everstiluutnantti is the commander of a battalion or a chief of staff for a regiment or brigade. The rank requires completion of a staff officer course.[2] Only a few reservists have obtained the rank of everstiluutnantti. It requires active participation in national defence and a demanding wartime position.
