The most amusing units in a Landsknecht formation are the Doppelsoldner, or Double Soldier. These are more experienced soldiers who take the frontlines, hence the riskier jobs. For that they are paid double - hence the name Double Soldier. Their primary armament is the extremely large, 5 to 8 feet long Zweihander - or Two Handers. The romanticized version recounting the use of the doppelsoldners were that they charge in with the zweihanders breaking spearheads of enemy pike formations so the rest of the Landsknechts can break through. Truthfully zweihanders were probably a pain to handle on the battlefield - tossed away after the initial contact and drawing their common use sword - the Katzbalger - for close combat when the enemy lines are broken.
