I also like how they didn't bother to upgrade Sergeant Culn and he still has 25 mm base and Mk VII legs/arms/backpack in the pic advertising Mk IV box. They could refresh random dudes with largely identical parts to new bases but not centrepiece character that could really use picture showing full Mk IV look?
Slight point of pedantry, but that's not Sergeant Culln, it's Sergeant Haas. That PA upgrade kit is originally from Anphelion, which first introduced Culln as a Captain (Commander) in his TDA. There was a Sergeant version of Culln, from Vraks (because that campaign was set earlier in m41, despite a few timeline errors in the story), where he led an Assault/Vanguard squad (can't remember which, maybe both, as the Scorpions did deploy to Vraks twice) but that hasn't been redone in this re-release.
