I see. To me that says they are essentially grenadiers, which serve the same purpose as Storm Trooper and have similar training and gear, but are strictly a part of their regiment and are trained on their home world instead of the schola. I don't think it warrants changing the Storm Trooper entry in the book though. If you want to build a grenadier for your regiment you only need to take use the Storm Trooper as a starting template for gear and talents and such. After that you can write whatever story you want. I've done this with one of my characters and its really simple, to the point that no house rules are needed.

I don't think you've realized yet, MILL, I am that same player. I will probably be posting the regiment and planet information for the Aestans on here at some point. Probably after I do some editting passes.
