|“||Ships 10 of the famed Wild Geese (Harquebusiers) from Ireland.||”|
Wild Geese is a technology in Age of Empires III that is unique to the Spanish and can be researched at the Church once the Industrial Age is reached and the "Royal Decree to Claim the New World" Home City Card has been sent. Once researched, 10 Hackapells named Wild Geese (Harquebusiers in the Definitive Edition) will appear in the Home City shipment point and all existing units of the same type will be renamed to Wild Geese.
- Though the Wild Geese in game are Cavalry, the historical "Wild Geese" (Catholic English and Irish exiles in Spain and France) formed Infantry regiments. The background for Ireland exiles was introduced in the Definitive Edition.
- In the Definitive Edition's game files Hackapell Wild Geese are set to speak Scottish Gaelic using the Highlander's dialogue files. This is most probably because Scottish Gaelic is closely related to Irish language, both of which belong to the Goidelic group of Celtic languages. This is not used in the game however, since Hackapells were replaced by Harquebusiers.
