Looking through the book, and the newest Errata, I've noticed a large number of things listed on the Career advancement tables, which are standard starting talents or skills for that career.

For instance, Guardsmen have Melee Weapon Training (Primitive) and Basic Weapon Training (Las) listed, Psykers have Psy Rating 1, etc

I was just wondering why these are listed as possible purchases if you cannot start without them

I believe it was said that the reason they did that was on the off-chance someone decided to let people buy into a different career path (or that there were eventually rules covering this), you'd know how much the starter skills/talents were worth - either for straight purchase or as a gauge for the cost of an elite advance.

Ahh. See, that was my first thought, and I checked through to make sure I hadn't missed some sort of existing rules for multiple career paths or something. When that turned up nothing, I was slightly confused. Ah well. Not like it hurts anything, I just couldn't figure out WHY. Thanks
