Red Grief can consolidate back to a transport after fighting, yes. I'm talking about a single movement phase. I disembark from my damaged transport, move 7" to be within 3" of another transport, and hop on board.
It depends if the rulebook wording is order specific, as it says you can't embark then disembark. Does that mean you can disembark then embark?
Thought I'd ask the question. It came up in a game tonight and I was trying to check it up quickly during play. Reading the rule again a little slower I'm fairly certain you can't!
