User blog comment:Lspec/Assassin's Creed III enemy types/@comment-4947517-20120409021324

The picture of the new archetypes that I was referring to in this post has since been uploaded into the article about the British Army. The sword-wielding soldier with the tall hat is the new seeker type, and the brute type is the kilt-clad soldier with the axe. According to some of the recently released information, these brutes are Scottish. The axes that they have are likely referencing the fact that sappers of that time period brandished axes for the purpose of breaking fortifications to make way for the regulars to charge in.

On a side note, supposedly French sappers of this time period, due to having such a high risk job, were given certain privileges such as the permission to grow a beard, and it's possible this similar principles might have applied to sappers of other countries' armies. This could be why the brute is the only enemy type we've seen so far that has on a full beard.

Also, it's also been confirmed that Native Americans will feature as enemies. Whether or not they will follow the agile archetype remains to be seen, but the chances that they will fill the role seem likely.
