I don't think there's a mod like that; it was a change to the appearance of swordsmen, not armored units, like for an alpha version of the game.
Our respected colleague, footman, made such a mod, but he seems to have cleared his Yandex Disk, so it's now difficult to find his mods.
There's a swordsman like that in the NVS mod, but it includes a lot of other things. The mod author is active on VK; you need to join the group first (screenshot from there).
Thank you, that's quite close to what I remember. Except for the color palette.
NVS is interesting, but I'd like to see more examples from the game.
And I assume there's no longer an active topic/catalog on the forum?
