[Rules] 4e 2x or 3x vs open top afv's with plane df

[Hugmenot]

My interpretation is as follows:

Let's pretend an aircraft is attacking a hex with Direct Fire and the hex contains:
1 x StuG IIIG
1 x GREN
1 x SPW 251  with 1 x GREN loaded on it
1 x SPW 251

The StuG IIIG is a close-top AFV and the SPW 251 is an open-top APC.

X Result
The owner of the aircraft may apply the step loss to the GREN OR the SPW 251 loaded with the GREN OR SPW 251.

An easy choice in this case.

2X Result
The owner of the aircraft may apply the first step loss to the StuG IIIG OR GREN OR the SPW 251 loaded with the GREN OR SPW 251.

The owner of the units selects the unit to which to apply the second step loss.

3X Result
The owner of the aircraft may apply the first step loss to the StuG IIIG OR GREN OR the SPW 251 loaded with the GREN OR SPW 251.

The owner of the units selects the unit(s) to which to apply the second and third step losses.
