Advancing to factory roofs......in RB

[Oberst Hausser]

Is it legal? Advance to RB factory rooftop.

Also per pp and MP remaining what "cancels" such an advance?

Example:

44 7 moves to factory roof ground hex (stairwell, or road entrance) not CX with MMG.

In the subsequent advance phase can the 447 advance to the roof? ( with MMG)

Same with 426 ?

The 447 moved and is now CX with MMG can it advance to the roof.

Same with 426. (with MMG)

I think in all cases the answer is no since it is not possible to move except by x>1 MF but
"may" be possible with LMG. Trying to figure out where the "cutoff" points are....


Thanks

I'm far from a RB/RF expert but I'll try.

Also per pp and MP remaining what "cancels" such an advance?

One restriction is that a CX unit can't advance vs. difficult terrain (A4.72).

447 moves to factory roof ground hex (stairwell, or road entrance) not CX with MMG.
In the subsequent advance phase can the 447 advance to the roof? ( with MMG)

As I understand B23.87, the MMG/447 can Advance to the rooftop since the ground and Rooftop levels are ADJACENT. It'll cost 3 MF, and the MMG/447 has only 2 (portaging 5PP) so the 447 becomes CX.

Same with 426 ?

A 426 with or without a MMG becomes CX because the cost is ≥ its MF (A4.72).

The 447 moved and is now CX with MMG can it advance to the roof.

Same with 426. (with MMG)

Neither can Advance since the 3 MF cost when compared to their available non-DT MF (1 for 447, 0 for 426) makes it an advance vs difficult terrain (A4.72). Since the 447 or 426 are already CX, they cannot advance. In fact, the MMG/cx426 can't advance at all since it has 0 MF available (it starts with 3, and has an IPC of 2 because it's CX, it's carrying 5PP, which reduces its 3 MF by 3 to 0).

Trying to figure out where the "cutoff" points are....

A4.72 sets the limits for advancing (there may be more for special circumstances, but start with this).

• If a unit has no MF after deducing for portage costs, it cannot advance.
• Define "Advance vs. Difficult Terrain" as an advance to a Location where the MF cost (excluding SMOKE) is ≥ 4 MF and/or ≥ the unit's available non-DT MF.
• Otherwise a non-CX unit may advance to a Location (and may become CX if advancing vs difficult terrain).
• A CX unit cannot advance vs difficult terrain.
• Otherwise, a unit can advance to that Location.

The "cutoff point" you are looking for is "4 or all the unit's MF, whichever is less".
