Fähnlein
The Fähnlein (in Swedish: Fänika) was a military unit approximately equivalent to the company or battalion which was used in parts of Europe during the Middle Ages. The size of the unit varied, originally a Fähnlein could consist of as many as 1,000 soldiers, but numbers were generally less, around 500. It was sub-divided into sections or Rotten (singular: Rotte) of between 6 and 12 men.
