There are some interesting things in there.
Models killed by exploding vehicles count toward combat resolution as long as the vehicle was involved in the close combat.
My favorite is the one where models embarking on a transport which rams another vehicle and is destroyed in the same movement phase cannot disembark and are destroyed.
What kind of crack do you have to smoke to even come up with that situation? "Hey guys, let's all get on this wave serpent and then crash it into something!"
