Drill Instructor existed in the old readme because this is an old mod-in-planning.

Should be fixed now.

If you're checking the HTML readme, it accidentally wasn't been updated. Drill Instructor has been replaced by Heroic Legend, which can be found in the Markdown readme.

A fix should be in soon.

Nice mod! Drill Instructor is exactly the same as Improved Warlord from the second DLC. Not sure if that's an oversight or you wanted a similar option for people who aren't using that DLC? Maybe make them mutually exclusive.
