Wait, I'll grant for the sake of argument that your position is supported by the rulebook. But the FAQ? Your position permits a squad in reserve to split into combat squads, thus permitting one combat squad to embark on its dedicated transport (if it is also held in reserves) and the other to remain on foot in reserves. Whether or not the rules allow this is, practically, the major point of disagreement between our two positions.
The space marine FAQ says, "Q: Can you take a Drop Pod with a 10-man squad and then put a combat squad in it, deploying the other combat squad on the table or leave it in reserve but not in the Drop Pod? A: No ..."
Right or wrong, authoritative or not, the FAQ clearly disagrees with you as to whether you can split a squad in reserve and deploy one combat squad in their dedicated transport if that DT is a drop pod. I see no principled distinction between a drop pod and any other transport (say, a Razorback) that would cause us to think the FAQ would answer differently if the question was, "Can you take a Razorback with a 10-man squad and then put a combat squad in it, deploying the other combat squad on the table, or leave it in reserve but not in the Razorback?"
You do?
