One career path I've found missing from core RT is that of an army commander. The arch-militant has a limited number of leadership skills that can only be chosen fairly late. The Rogue Trader has quite a few leadership skills, but being the overall leader of the entire enterprise his skill selection is very diffuse, it makes sense that he'd have a subordinate specifically to command his troops, from the armsmen aboard the ship to divisions of ground troops for waging planetary war. Thus I present you the Marshal career path, a work in progress by me

As you can see, I've filled out all ranks up to 4, about half of 5, and sporadically a little this and that of ranks 6-8. I'm temporarily out of ideas on what more there should be there, so I'd appreciate suggestions. And if you have any general criticism of the content already in, let's hear it.
