So lots of people have played it incorrectly.
Hopefully this topic and the PDF structure will lead them to play it correctly now
Could you please explain exactly how it must be done ?
If a TUG passes through a friendly SUG any displacement is restricted to the minimum necessary with a maximum of 1BW* and not the unlimited displacement that some, many even, have played previously (no doubt for various reasons).
Note, however, that in the case of passing through a friendly SUG the displacement must place the SUG "behind" ** the TUG; in other cases such as the displacement meaning there is no passing through, the displacement could be in any direction.
I think a key thing to remember is that it is a displacement, and thus 4G applies.
And will there be an update with it in the available PDF ?
IMO the wording in the updated PDF is sufficient (and pretty much as the 1st release of the PDF), although as noted the diagram in 4F could be improved but that will have to wait.
* usual restrictions about not displacing the SUG into shooting range of enemy it could not previously shoot at, etc.
** no doubt this will now cause a discussion of what is meant by "behind"; IIRC we had one a bit back so a check for that may help head off some of it
