Pocus will give more details if I am wrong, but the script is better suited to remove ALL units of one faction. Here is the example taken from the events in NCP's Prussian Campaign 1807
[color="DarkRed"]SelectSubUnits Area $Theater_Germany|FactionTags SAX
AlterCuSubUnit ApplytoList|Kill[/color]
Here, what it does is select all kind of SAX (saxons) and remove them from the Germany theater...
Now you could do something like:
[color="DarkRed"]SelectSubUnits Area $Deep South|FactionTags IND
AlterCuSubUnit ApplytoList|Kill[/color]
This would remove all IND units from the Deep South (could be used for a Peace Treaty implementation, or even for some Indians changing side)...
However, I suggest you keep on using the RemoveUnit script for those merchandises...
