Question on tactics: Assault, assault and assault

[Glint]

:chin:
Had a quick peruse of the messages and thought to myself,
if one treats a move as six minutes, an assault with a mix of Infantry, armour and half-tracks can only be done one hex at a time? Whatever order the units assault in, if you finish the assault off with empty half-tracks that are in the vicinity of the other units, surely within the six minutes, it's reasonable to consider they were part of the combined force and supported, albeit beforehand? Quite acceptable I would have thought although I would rarely do it myself but using the halftracks to close a retreat hex is also acceptable, I would have thought?
Just a thought, a big one, lol!
