Add more types of mercenaries?

[Riddle]

I'm just wondering what files deal with mercenary recruitment. I want to add some new types, but I don't know where to begin (outside of module_troops.py)

FWIW, I would have used the search function but I think its broken at the moment.

The game defines two troops as the beginning and end of a range of mercenaries (in module_constants). These are mercenary_troops_begin (Watchman) and mercenary_troops_end (a placeholder troop). As long as your new troop is within that range, it will be considered in the random selection when script_update_mercenary_units_of_towns (in module_scripts) is called.
