I found some UU's unique abilities carry over when upgraded while others lose theirs, and there doesn't seem to be any set of rules.
For example, American Minuteman(musket man replacement) retain their ability 'Ignore Terrain Cost' when upgraded to rifle men, making them extremely versatile when fully upgraded to mechanized infantry, while Spanish Tercio(also musket man replacement) lose their ability 'Anti Mounted' when upgraded to rifle men.
Does anyone have a list of which UU's special abilities carry over and which don't?
