Can you vault and, while still vaulting, vault again to a higher platform? Take a look. The Mowang vaults onto but not over a short wall that can't support him, then turns and vaults over a wall that is taller than him in his staring position but not mid vault.
"A trooper can vault over any obstacle not higher than his Silhouette Template (as determined by his Silhouette Attribute) at no cost, without declaring Jump or Climb." What you're describing isn't really 'over' an obstacle.
Until now we played it the way Cmdr. Gregmurdock described. As long as something is lower than the silhouette you "pop" up there. You can also be on a space (like the wall) that is not able to support your base, as long as you don't end your move there. From this mid-move-position you are able to act without restrictions. You can move further to other obstacles. We purposely build small crate caches to help the miniatures move on top of sheds and other low buildings. Actually, it is the same principle as stairs are used... or not?
If it's a section of stairs you define it as a section of stairs prior to the game, you don't use the vault rule to climb stairs. You can stop in the middle of a stairway, you can't while vaulting.
Uh, good point! Well, it is a question of declaration - before the game starts. In this case, the situation above could have been both - allowed and not allowed. It just had to be declared as an intentional "staircase". This option helps to make some region just more accessible.
"large enough to support bases" is like "big enough to grant cover" (or "tall enough that the top sliver of a model won't be visible"). It sounds simple until you're reminded of the fact that there's more than one base size in the game. So you build something wide enough for an S2 model to go up without vaulting, and then someone puts a TAG or remote next to it and we get "Multi Vault Drifting 2: Base Size Runaround".
Different pieces of terrain are built for different size models to go up. Not every spot is an entryway for every model.
Where does it say this? What about just vaulting onto something. That's not over either. Also, can anyone point out the page number or wiki link to the diagram that shows how vaulting works? I've got someone saying you go through while I'm pretty sure it's up and over.
Onto and back is the same path as over, so it's generally allowed. It's not particularly clear though. You measure through and the SIL moves up and over. As per the FAQ: Q: Can troopers move through obstacles that do not exceed the height of their Silhouette Template? Then is that movement considered “up and down” or does it count as if they were always at ground level?A: Troops can vault and they are considered to be moving “up and down”. http://infinitythewiki.com/en/General_Movement_Rules
Where does it say your model is allowed to stop vaulting? It's implicit all over the General Movement Rules that inane.imp linked. Other than while vaulting your model's base must be fully supported, so when you stop your vault mid-vault your base is no longer fully supported. "But" you say "I'm already in a new vault at that time". So you're now arguing that you can vault any obstacle, no matter how tall (even the Armoury because infinity+1 base > infinity) provided the obstacle is not perfectly perpendicular with the table or leaning over the table? Besides, it's implicit that when vaulting you have to define the vault's end point, which again must follow the General Movement Rules. So do your self a favour and start defining features like these as stairs if you want to climb them. Implement an access height rule ("you must be this tall to walk the stairs") if you must. Don't rely on the physics engine for these things or you'll end up with every model being a horse from Skyrim.
