There were claims that some Russian eyewitnesses had affirmed that an airlift and truck convoys had moved a lot of stuff to Syria before the Marines showed up.
Also, don't forget the biological research: Dr. Death's research complex, which had been video'd intact in February before the invasion, was revisited by the same PBS TV team after the invasion and found stripped of its files, equipment, storage, everything.
Thanks for the mention. It was tough to keep up on some aspects and I either missed this or had forgotten about it.
