How about in the Drop Pod rules? Page 69, Codex: Space Marines, page 32, Codex: Blood Angels, page 47, Codex: Space Wolves, and page 22, Codex Black Templars, all have a line in the rules stating that a unit cannot assault the turn it arrives via drop pod.To be specific: assaulting out of a drop pod. Why is this not possible? Can someone show me where it says you can NOT assault out of a drop pod?
Dark Angels didn't have that line (such are the perils of an old codex), so they FAQed that one.
