So, like a not-quite-so-special special forces?
I looked these up on Wookiepedia, and found this:
They (Death Troopers) managed to annihilate the remnants of the Rebel strike team. However, the entire squad was killed by Baze Malbus and Cassian Andor shortly before Krennic's death.
Well how about that. Yeah, so I guess the Empire was like, "we should train less troopers but train those more" and boom. Inferno Squad.
I agree completely, that was the point I was trying to make.
Also, upon more Wookiepedia research, I found the hovertank was actually never in Rogue One. Instead there is an assault tank that doesn't even float, it rolls on tracks. Doesn't sound great for Hoth travel. While the hovertank was in concept art and in Rebels, toy companies (including Lego) named their products after the concept, not the final version. Not the first time Lego has made a "mistake" like this, just look at the first Ten Numb minfigure. And then Lego makes concepts into sets as well, like the Heavy Scout Walker in the Last Jedi sets, though I'm not convinced those are mistakes rather than just what they felt like doing.
