Some might remember this from Operation Arrowhead: Certain heads from special campaign-centric units/characters would not always look the best on some standard player models, hence why there were usually hidden in the Player Profile.

I suggest having some way that these special heads are slightly altered so that either their head geometry or hair does not extend beyond the model of the applied headgear, so that a player has the freedom to choose whatever head with whatever headgear they wish, and not look silly. {F16847}
