Where to find unit files?

[killerbannana_1]

Hello, I am interested in duplicating and creating some new units for my game (just modifying the stats a bit and editing the models/visuals maybe to create some alt-history unit types.) I scoured the game files looking, but was unable to find where they were at.
So my questions are: Where are they, and is this feasible to do? it wouldn't be too complicated of edits. And all would it be possible to convert the unit models to .obj or .stl so i can edit them to look a bit different in blender say? Or are the visuals done in a different way.

Very new here but a decently long-time player of this game, thank you all for any help.

It is wise to create a backup of the units-file before editing
