How would you architect for a Turn-Based wargame - stand of 10 infantry?

So I’m still fairly new to unreal. I’m stuck on a problem and need some ideas.

A selectable unit in this game is a “stand” which is a rectangle that contains a row of five infantry models in two ranks (so ten models altogether).

I have a pawn object. Should that pawn object represent one of the infantry models? Even though you move the stand of 10 guys as a whole? Or should the pawn object be the stand that holds the 10 infantry meshes?

Or is it one pawn that is a container for 10 pawns and the parent pawn is the overall selectable object and controller?
