Good day gentlemen, I'm new to MTW and have a couple of questions in regards to modding. After reading quite a few of the posts in this forum I have a "reasonable" understanding of how things work, but need to clarify some simple things.. bear with me..

1. Is it possible to add a completely new unit to the game without modifying an existing one? New name, new stats etc?
2. Can the main campaign map be changed.. borders, place names etc?

Thank you sirs.
