Ace from Rainbow Six Siege is a Norwegian character that stems from Lærdalsøyri, Vestland, Norway. His full name is Håvard Haugland, a very believable name, especially from Vestland. His voice actor is Kyle Gatehouse, a Canadian actor and writer.
His voice lines sound more akin to a German accent than they do a Norwegian accent, and he is unable to pronounce is own name (pronounces it Howard, not Håvard or anything close to it).
Verdict: His ass is NOT Norwegian.
Fun fact: Nøkk is a Danish operator with a Norwegian name. Her voice actress is also Canadian, but has obviously taken time to learn what Danish English sounds like.
