Keep in mind that they might be using initial Ghost team models for the trailer. But apparently, we can see here that apart from holding ACR spotted, our teammates have their unique attributes back. Most highlighted one is Midas.

Midas has his machete vest and bloused boots back. See these pics.










Weaver also seems to have his grey-blue hoodie back.




Unfortunately, at the sample of 'Remove Teammate' feature, the models used are the models after Spec Ops 1 where our teammate lost their unique attributes.




Again. Keep in mind that they might be using initial Ghost team models for the trailer.
