Support fire is normally considered purely in terms of those enemy units that have actively participated in the assault. We agree that support fire cannot take place where those enemy units have died or did not actively take part.
However here the support fire is in range of units that are still alive but no longer actively participating in the assault, although they were involved earlier on in the assault. So are they still "involved" or not?
(note, at the end of the 1st round they [i]were eligible targets for support fire as they were involved and had not been killed during the assault)[/i]
To me at least, it is still far from clear whether such units can be considered to be 'viable targets' or not.

They would still be involved (part of the assault for outnumbering,taking hackdowns,consolidation,breaking from losing etc.) but not "directly involved" as stated in 1.12.6 (highlighted relevant part)

1.12.6 Supporting Fire (addition/change)
Both sides may call upon support unless the defender has been wiped out or the attack stalled as described above. Calling on support allows units from other formations to attack with their firefight value if they are within 15cm and have a line of fire to an enemy unit directly involved in the assault. In this case ‘directly involved’ means belonging to the attacking or defending formation(s) and in a
position to attack. This rule represents units from both sides that are not directly involved in the assault lending supporting fire when they see their friends coming under attack. Units from formations that are either Broken or Marched this turn cannot lend support.
It would make no difference from 1st round of combat to 2nd/3rd//4th/Nth round of combat.
If there is a viable target you get to support, if no viable target you do not get to support.
Any formation that was in position to lend support, at any stage of the combat, that was on the losing side would also take a BM. Even if it was eventually out of support range.
( from 1.12.8 )

Finally, any formations belonging to the losing side that were in a position to have lent support (ie, they were within 15cms of an enemy unit in the assault) receive one Blast marker each, even if they did not actually lend support. These Blast markers represent the detrimental effect on morale of seeing friends defeated in an assault.
