So guys, um the argument you are all having is moot since not everyone in this RP is likely to be jammed in the same vehicle. There is a huge war going on there will be multiple transport vehicles etc. Furthermore I don't see the point of getting all bent out of shape over something as insignificant as "Who can fit in what vehicle." If the vehicle can fit 10 space marines it can fit 5 space marines and 5 IG and a couple inquisitor while you tie a sled to the back for a minotaur to ride in (Last part being a joke.) the thing is at any given time if you guys are moving in a vehicle there will be other vehicles with you. You might like two chimeras and a rhino rolling around or a couple of valkyries and a vendetta. (Storm Talons don't transport they're VTOL gunships/Escort crafts) They are really cool though. So let's stop being so close minded (This isn't space marine) you won't be wandering around just with the 12 PCs you will be moving alongside plenty of NPCs and have plenty of NPC drivers etc transportikng you etc etc.
