How does UnitReplaces work?

[Dwane Diblie]

Is UnitReplaces limited to civ unique units replacing regular units only? I want to use it to replace a regular unit for all civs with another version of the regular unit for all civs. Is there more to this than just the UnitReplaces table?

UnitReplaces is for Unique versions of units that literally replace the default unit everyone else gets to use.

I want to use it to replace a regular unit for all civs with another version of the regular unit for all civs.

Not really making much sense to me.

If you want to add a new unit to the game -- just add the new unit to the game.

If you want to alter the prereq tech or civic for a unit, or its combat power, etc., then just make Updates to the needed tables to do this for that unit: Units, TypeTags, UnitAbilities, etc.
