Some players are very obsess on certain Unit. So they request to add new squad from that unit into the tech tree. But think about it, is it worth it to grind a new squad just for the name of the squad?
So here is the suggestion. Make unit name of a squad a customization. It will change according to the campaign.
You can select the squad unit name you want for a particular campaign.
Not only did the squad name and emblem will change, the default customization for the squad in the campaign will also change according to the selected unit.
*This will not affect the purchased customization, it will remain the same.
*To avoid confusion, the squad name will remain the same in the squad selection.
For example, if you select a Fallschrimjager squad for Berlin campaign, its default customization will also change to it.
Possible extension:
We can also apply such mechanism for Italian and British squad so everyone can have a full Italian/British squad line up before dev actually add them as independent/sub faction.
