What is "korpralskap"

Korpralskap is a Swedish/ Finnish military unit of 25 men split into four rote with six man each that existed during the 17th and 18th century—quite similar to a platoon today. The unit was led by a Korpral and in turn consisted of four rotes of six men each. Each rote was led by a rotemaster. A foot (infantry) company consisted of two piker and four musketeer korpralskaps.
