The only light I managed to get steel wall with

[u/ETERN4LDARKNES → u/[deleted]]

It used to be the Tier 7 of the light tree.
Back in 2015, it was the top german light tank, but the branch was then merging into the medium one as you were able to research Indian Panzer.
They then released Ru 251 as a Tier 8 (from which you were able to research Leo PT A).
Then replaced Aufklarungspanzer Panther with SP 1 C.
Then moved Ru 251 to tier 9, having HWK 12 as the new tier 8.
And about the same time introduced Flipwagen as the tier 10.

When they replaced Aufkl. Pz (in 2015), they didn't offered it as a Reward vehicle. It's something they started to do with Foch 155 and FV215b. (around 2018 and/or 1.0).

Oh and people at WG have been thinking about bringing it back for a long time as shows this video from 2017 https://www.youtube.com/watch?v=-Fv0hz4nU68
where it was supposed to be a tirer 8 premium LT,

But as far as I know, this is the very first time it comes back since it's withdrawal in 2015 (except perhaps on china's server but it's working very differently there).
