When it comes to the Battle for Middle-earth games, I am the maker of the Easterling faction for each one. That said, I have made extensive amounts of undeniable progress towards this end goal.
Once you've upgraded a Red Vipers' Dojo to Rank 3, you get to deploy two versions of this unit, and these footmen with the Battle for Middle-earth saga Elven archer animations are one version.
The other version consists of these guys on moderately armored horses, and when I say "moderately", I mean only the front halves of their horses are armored.
