The new AoS apparently treats the exact equipment of a lot of units as largely cosmetic, so whether or not they have shields probably doesn't count.
Edit: I mean, I think that's more of a good thing? Nothing was as annoying as having a bunch of shiny new models you could equip with weapons that were either cool, or weapons that the meta demanded were useful. Also because the meta changes constantly and a ton of models always gathered dust on shelves. Now it's "just do whatever you think looks cool" with older kits and the new kits are geared towards that. I for one am not sad about that, because sure enough whatever I wanted to equip anything with usually wound up being less useful rules-wise.
