Doppelsöldner
Doppelsöldner ("double-mercenaries", "double-pay men", from German doppel- meaning double, Söldner meaning mercenary) were Landsknechte in 16th-century Germany who volunteered to fight in the front line, taking on extra risk, in exchange for double payment. The stated ratio was that one Landsknecht in four would be a Doppelsöldner. The Doppelsöldner of each company were usually issued with ranged weapons, such as a crossbow or an arquebus, and arranged in the wings of a square, in front of the pikemen.
