Breakthrough!
Turned out I wasn't using the most recent version of Koshling's app. After searching 100+ pages of the ideas thread for the word "scanner" I found one that manages to export the tags I previously couldn't!
So
@Koshling, no need to look at my templates now, a more recent version of your app fixed them
EDITS
a) I also found why the Apache Cavalry had all its data in the wrong columns...commas
b)
Now that all the tags are working, can I trust C2C_CIV4UnitSchema in the Assets/XML/Units folder to contain all the tags that are used by the units in Assets/Modules?
