Much like the additional expandable list in the loadout list in Zeus, perhaps each unit side list can also have an "Arsenal" section, in which you will spawn infantry allied with the specified side equipped with your loadout.
Example, you select Blufor, Opfor, or Indfor in the Zeus "Create" pane, let's say you select NATO, the expandable faction categories would be listed as such:
Arsenal
All
FIA
>Men >Cars etc...
Nato
>Men >Cars etc...
And for both other sides, Indfor for example:
Arsenal
>All
AAF
>Men >Cars etc...
Then if you would expand the Arsenal category you would have units named after your loadouts that would spawn fighting for that given side with that loadout.
- Also: We need a 2D editor version of the loadout module accessible in Zeus. {F24347}
