Well by Gwar reasoning (it scares me to say that I am trying to think like him in anyway

) then I would say yes; they could indeed assault.
For me I would say this. If a unit turbo boosts and at the end of the turbo boost move they were within the 2 inches of an
IC you would have to take the turbo boost +4 cover save but could not take anything that came from the
IC that turn.
To me that would be the fair way to do it. And then next turn act accordingly.
That is a really good question though. I have never come against that one. I could see where it could be abused big time.
