How can i change the army names?

I saw in the New Army Mod or whatever its called that they changed the general names of the armies, how is this possible?

Here is the answer if i understand correctly:

Go to Scenario >> Player Properties.

Here you will be able to edit the player names. I hope this is what you were looking for!

Well im been thinking and this i do not know, i havent looked on the files too well, im think he is looking to change the races names, like Demons instead of Night Elves.. ill try to find out.

Thx Kerry that was what i meant..... Example Humans to Dwarfs or something like that!
