Seems pretty clear to me that the MMC can create a THH, as there is an AFV within 8MF. Assuming the THH roll is a success, the THH must conduct a banzai charge toward its designated target, per G1.423. A Banzai charge is a HW, but can start ADJACENT, per G1.5. A location is ADJACENT to itself, and an AFV in bypass is usually considered in the same LOCATION as the hex it's in. A unit ceases being a HW unit if it starts an impulse in the same location as a known, armed enemy unit, per A25.234. A THH can attack it's designated target in the MPh, again per G1.423.
So the unit in the same LOCATION as the AFV, in its MPh, creates a THH. This THH immediately conducts a Banzai. At the beginning of it's first impulse, it immediately ceases being a banzai unit, having expended 0 MF, and may immediately conduct a CCV attack against the AFV, remembering to roll for ATMM as appropriate.
The lesson here? Don't try and sleaze freeze GO Japanese MMC without killing them immediately afterward.
