Hi,
I agree totaly with the wwg, as they do not have enough movement to expand in the first place.
I do not agree with the "single Element move" argument at all.
The rules go like this:
Under Movement Section there is
1. a chapter on single element moves. There some Wheeled thingies (wwg and exp) and ships are forbidden to turn to flank but may turn 180 degrees only or by pivot or wheel.
ok.
2. a chapter on group moves. There there is no exception on who can do group moves. Group moves have a specific move patern, i.e. move the same speed or through the same angles EXCEPT as detailed in some special rules on formation changes.
ok.
3. Now, under the said formation change rules there is the provision, how to expand. There the sentence reads "the other elements move as by single element moves".
As I see it:
The "move as single elements" is NOT meant to preclude the exp and shp to leave the column. The Rules on Formation change etc. do NOT exclude Expendable. The "move as single elements" does mean, they need not conform to the normal group move restrictions, i.e. moving same speed, same angle etc.
If this was not so, the sentence "but not exp, wwg, shp" would have been much easieer, than "move as single elements". It is NOT intended here to exempt exp from the posibility to expand from column into line, but to free all Elements of the group move restrictions.
I see, that the wording is open to debate, but the simple conclusion that the sentence "move as single Elements" does IN EFFECT only mean "exp and shp may not expand" (wwg can not for want of speed) is contrary to the aim of the rule.
This would in effect mean, that ships could not go from column into line, also this was a comon manouver in reality for what I know.
Ships invariabl marched in columns but before they fought in lines with broadside to broadside, they formed in Lines bow to bow to fight each other, galleys and ships indifferently.
I do not know about exp, but would thinks they too came to the field of battle in column and expanded into line.
In the end, to expand from a "moving" (last move) column into a line IS different than to leave a (standing) column.
As the rules are meant to simulate somehow the reality, this -for me- can not be the conclusion.
