Modding Question(s)
i've been working on a few mods in the last few days. i'm currently making edits to the db > unit to unit abilities junction table > unit to unit abilities junctions and have run into a few terms i'm unfamiliar with, hence the post.

towards the bottom of the table is 3 modifiers Sh_ UP1_ and test_. there is also one unique entry called "Shogun_infantry" that is the only Shogun_ modifier of it's kind. i need help identifying what those 4 prefix's mean so i can finish writing this mod up.
