There wasn't much to begin with back in RT (see stickied thread) and what little there was was removed in 2nd ed. They got three infantry-models in metal (I think there were 3), a statline and a blurb, that was pretty much it. Not a lot to go on, so the fan-made lists I have seen are quite commonly dumb and very... stretchy, as far as concept goes.
I am sure you can write something up though, should you feel thus inclined.
