I notice that some of the listed Regiments don't seem to have the gear that would be appropriate per their Regiment creation rules.
For example, the Ogryn World sample regiment doesn't list the 2 krak greandes they should get from being a close assault regiment. This is likely because such grenades are not Ogryn-Proof. Does the regiment get the ability to 'trade-in' such items for something more useful to the whole regiment? I notice that they have 5 frag grenades (more than the 3 frag grenades typical to the Close Assault Regiment). It's possible they bought these with points, but could they also have traded in the krak grenades for them?
As for the Crimson Guard, I have no idea how they got so much rare equipment.
