Hmm. I'm not seeing
=any= mention of MPs (or their targeting) in D5.42, so, I’m not following you, here.
That's because it is mentioned as related to the Crew MF expenditure in
"D5.42 ENTRY: An Infantry unit may enter an Abandoned vehicle to become its Inherent crew only if it occupies that vehicle’s Location at the start of its MPh (not APh) and expends all of its MF to do so [EXC: CCPh; A21.2]. It may also attempt to hook up a Gun as it does so. See also 5.43. A vehicle may not be entered during the same Player Turn in which its previous crew left [EXC: CCPh; A21.2]." and,
"D5.43 FFNAM: ...or the vehicle’s simultaneous MP/MF expenditure (6.4; 6.5)." and the Example of D5.43,
"EX: An Infantry Unit attempting to enter and Inherently crew a vehicle (or attempting to load on to any form of transport as a Passenger/Rider) does not succeed—and also fails to hook up a Gun if it were attempting to do so too—if, due to defensive fire prompted by that MF/MP expenditure, it is pinned, eliminated or loses its Good Order Status (or the vehicle is destroyed). An Inherent crew attempting to Abandon a vehicle (or a Passenger/Rider attempting to unload from its transport) does succeed—but does not unhook a Gun if it were also attempting to do so—if it is pinned, eliminated or loses its Good Order status (or the vehicle is destroyed) due to such fire."
I'm not seeing that D1F is
=clearly= allowed by any rule vs any ASOP Step D3.22A activities. There’s a very long list of activities in ASOP 3.32A. For whatever reason, =simple= Crew entry/abandonment of a vehicle is not in the 3.32A list (where D1F =is= allowed), but in the 3.22A list (where D1F is =not= allowed).
That's because in the ASOP Step 3.22A is a subset of each unit's MPh...3.2A is a subset of "3.2 START of ITS MPh". So, at the START of ITS MPh a crew must announce its intention to Abandon its vehicle and mark the vehicle Abandoned. (this is the same thing you do for units that are Banzaiing for example) Then you move to the next step "3.3 DURING ITS MPH", skipping 3.31A as there are no Berserkers moving now, to 3.32a where the crew (as are all other units) is allowed to actually spend the movement (all in this case) to perform the action just announced in 3.2 above.
I see how the D5.43 EX may =seem= to say D1F is allowed vs simple vehicle Crew entry/Abandonment, but I think the (more loosely worded) EX is (too tersely) referring to both simple Crew entry/Abandonment =and= to the same plus Gun Hooking/Unhooking (C10.11, C10.12). The latter occur in ASOP Step 3.32A, where D1F =is= allowed.
Incorrect, NO action that requires actual MP/MF expenditure is performed in 3.2...this step is only for ANNOUNCEMENT of intended action.
Note that attempting to Inherrently Crew is not an activity subject to D1F
=unless= done in a manner found in ASOP Step 3.32A.
The act of spending Movement Points/Factors to (voluntarily) Crew or Abandon a vehicle is allowed ONLY in 3.32A...This is the only place a Good Order Unit MAY move during its MPh.
So, I'm seeing the Crew subject to D1F only if also trying to Hookup a Gun, say. Otherwise, simple entry occurs in ASOP Step 3.22A (no D1F, therein).
Incorrect, the Announcement of intent to Abandon/Enter is done in 3.22A where is says (Pepare to Move)
Well, your opponent may prefer to Abandon in that D1F-free ASOP Step before the Passenger Unload.
Not possible.
Seems to me, if you =only= want to Abandon/enter a vehicle, you accomplish that, w/out fear of intervention via D1F (perhaps that seems odd), owing to the ASOP. (In both cases, you might get whacked in Final Fire, of course.)
Maybe this "D1F immunity by warrant of ASOP Step 3.22A" is intended; maybe it isn't. But, unless I've missed something, it seems to be the rule as written.
