I cannot follow the discussion here
W/out getting into the weeds...
...there was a (near invisible)
problem w/A7.55.
J13 errata gave a solution which (in the eASLRB_v2.03 -> _v20.4 update) was =not= implemented when it could have been.
Instead, the _v2.04 update implemented a
better solution (one which addressed the problem but, by leaving in, "Good Order," w/
fewer side-effects).
=-=-=
In sum, the unnecessary J13 A7.55 deletion-by-erratum of "Good Order" has not been implemented.
Instead, text was only added to A7.55 as highlighted below:
eASLRB_v2.04 said:
A7.55 MANDATORY FG: If Good Order units/weapons capable of forming a FG with each other in the same Location are going to fire at the same target (i.e., at both the same Location and the same unit and the same “simultaneous” [8.1] MF/MP expenditure; see D3.5) during the same phase they must form a FG [EXC: Fire Lane; 9.22]; they may not attack separately except with ordnance/FT/DC or the subsequent shots of multiple ROF weapons (9.2).
This moment, being the more recent verbiage,
the above is the Official rule, so, ignore the J13 directive to delete "Good Order."
=-=-=
[Given the evolution, I
expect the J13 erratum for A7.55 to be rescinded and an erratum published to bring about the eASLRB_v2.04 A7.55 text above instead.]
