Yeah, anyways they're one of my favorite two in gmod because most servers make them both ARC or at least 29 is ARC

It is indeed never stated that they were part of the 104th, but it can be assumed.
Four-four's name is indeed stated in the comic, however, the only thing we know about CT-1129 is that his name started with "Nin" and that's all.

And awesome thanks for telling me

Those names are real and what I said about the are real but they aren't attached to a specific battalion just worked with 104th

Sadly I haven't found a way to edit the faces of the troopers. When I do, I will edit him of course.
AT stands for "Anti-Tank", so basically outfitted with RPS-6 or even PLX-1.

What CT-1044 and CT-1129 concerns; these are the names we used in our old battalion for them, so these are the ones I used here as well. I do not believe either of their names are actually confirmed in canon. Artistic freedom, I guess?

But I am glad you like them. :)

Another thing, fourfour and nines were also called Dash-44 and Dash-29 and I believe Nines was called Niner but eh it's whatever, don't think me saying this is a bad thing, I'm only saying this because I have zero actual complaints about the models except for what I've already said :)

One thing, Wolffe doesn't have the cybernetic eye but has the scar on his face which I find odd
Also, what does AT stand for?
