A forlorn hope is a band of soldiers or other combatants chosen to take the vanguard in a military operation, such as a suicidal assault through the kill zone of a defended position, or the first men to climb a scaling ladder against a defended fortification, or a rearguard, to be expended to save a retreating army, where the risk of casualties is high. Such men were volunteers motivated by the promise of reward or promotion, or men under punishment offered pardon for their offenses, if they survived.

The Landsknechte, also rendered as Landsknechts or Lansquenets, were German mercenaries used in pike and shot formations during the early modern period. Consisting predominantly of pikemen and supporting foot soldiers, their front line was formed by Doppelsöldner renowned for their use of Zweihänder and arquebus. They formed the bulk of the Holy Roman Empire's Imperial Army from the late 15th century to the early 17th century, fighting in the Habsburg-Valois wars, the Habsburg-Ottoman wars, and the European wars of religion.
