1) Is it correct that most non-MP/MF actions (ex: CE/BU placement, dropping SW, creating TH-Hero) can generally be declared simultaneously with [EXC: BFF] or before/between/after any MP/MF expenditure?
Some such actions certainly may be.
2) If yes to 1), Assume that an BU AFV expends a Start MP, possible drawing some DFF, before it then goes CE (without the expenditure of any MP). Is it correct that the DEFENDER may DFF vs the now CE AFV with all weapons that
has not yet fired, still based on the Start MP expenditure (since A8.1 generally allows DFF to be declared vs an MP/MF expenditure as long as a new MP/MF expenditure has not been declared)?
Yes.
3) A BU AFV declares that it simultaneously goes CE and enters a new hex through a road hexside. Is it correct that it must pay 1 MP since it became CE simultaneously with the MP, which is expended in the hex entered?
The new CE status would apply to that MP expenditure, so it could use Road Rate if desired.
Similarily, if a CE AFV goes BU and enters a new road hex at the same time, is it correct that it pays 1/2 MP and is BU vs all DFF?
The new BU status would apply to that MP expenditure, so it cannot use Road Rate, but would be BU against all DFF at that MP expenditure.
D3.3 says: "The DEFENDER can intervene to attempt Defensive First Fire after the announcement of expenditure of any MP (even Delay MP) but must do so before announcement of the next MP expenditure or of Bounding First Fire; the target cannot be forced to return to a previously occupied hex or CA after it has announced a MP expenditure that legally changes its position"
4) Is it correct that the above rule is a (poor) rephrasing of A8.11's intention, and only means to say that any DFF shots that is not declared before announcement of BFF, must be done *after* the BFF has been done? I.e. is the following sequence correct:
* AFV enters a new hex, expending 2 MP
** Gun chooses not to fire
** AFV declares and performs BFF
** Gun may now choose to fire based on the 2MP expended.
The above sequence is correct.
Some such actions certainly may be.
