Okay...That still leaves the Suzaku, the Dauntless, and the Dominion mobilized. Why is the Dominion MOVING? That was set down as the new base. The Dominion moving in concert with any other mobile fortress is going to have the support of the others. Also, if the Dominion is moving, the town is the new wasteland. A "There wasn't one before, but there is one now" sort of a thing.
I worked on the port scene with Etch, I'll send it to you later when I have access to it.
So you still have the Suzaku and Dauntless to deal with. The Yamato was specifically mentioned as present as part of his deployment forces. The Suzaku being present means that serious s*** is about to go down. Along with obelisk of light support from the Shinigami and anti-magic gas support from the Yamato. The Sky Ray must slip away from this engagement or face being flooded with napalm.
If the ships come from a wasteland and are on Lake Suwa, they have amphibious capability. They can still squash the town flat. My biggest problem is the Dominion moving since that means that the Council 42 said "f*** it, this cloak and dagger capture mission is not worth it. Crush them like insects."
EDIT: Um...Owlbear? The RAI were ordered to sweep up after the Suzaku flooded the decks with burning napalm.
EDIT2: Bah, this new shaping has imprinted itself deep in the story. I'll modify the briefing again. The RAI better be equipped with the special uniforms designed to handle being covered in napalm and gas masks.
