In the case of some Artillery like Sabre Weapon platforms, the model comes with a Crewman who is a part of the model, actively manning the Artillery but the unit says it comes with a single Crewman per Platform. I assume this Crewman is separate and needs to be based on a standard 28mm round base since as I understand the Artillery rules, a Platform cannot fire on it's own?
In this case, if I upgrade with an additional Crewman, I then need to base another 28mm guardsman separately?
If this is true, then what is the point of having a human figure firing the gun, other than aesthetic purposes? I had considered putting 2 Guardsmen on the Platform, magnetized, to represent the 2 wounds per Platform, but it seems like misrepresentation since they are not the ones actually firing the gun.
