I am still working on this mod and i will be adding more troops soon. There's only 14 unique troops at the moment. 
<br /><br />
<br /><br />Allows certain troops such as: Swadian Recruit, Looter, Farmers, Sea Raider, and other outlaws to be upgraded to custom Troops. (They're not over powered and use simple items like leather, mail, and use simple weapons aswel.) I use odd names like "Ground Knight" so i don't interfere with already existing names of units.

     Trees:
               Looter: Thief: Master Thief.
                           Thief Archer: Master Thief.
               Farmer: Soldier Trainee: Trained Infantry: Guard: Ground Knight: Trained Cavalry.
                                                    Trained Archer: Archer: Trained Sharp Shooter.
               Most Bandits: Hired Outlaw: Expert Outlaw.
               
               Swadian Recruit: Swadian Fighter: Swadian Archer.

               +More!

 Those are some of the current unique classes at the moment. I didnt remove any pre-existing classes.

           Post a comment of what i should add, and ill probably add it within 2 days.
