Which of these words is derived from the name of legendary Scandinavian warriors?

Berserkers as I understand were wild and ferocious, and during those times of large swords and heavy armor, they employ a different tactical advantage of wearing no armour and instead rely on their speed and agility versus brute strength... 🤔 just a thought 😅😊

new info for me.thanks

Major Naive Cube, I’m not sure that the time of the Vikings and Berserkers was a time of heavy armour. I think that was more the start of the Middle Ages.
