The regiments I enjoyed being in was the I15, ran by Ahonen.
It was my first regiment, and I started out as a recruit.
I then recruited lots and lots of players, was very active, and was promoted to Colour Sergeant.
Then the I15 expanded, adding one cavalr dragoon company, and one line company.
I got promoted to Captain, and was given that second line company. Unfortunately, the company wasn't active and we didn't grow much at the time... But I ended up in being the officer who gave all the trainings. It was AWESOME.
