Thanks & Question regarding opportunity fire

Another interesting aspect of the WinSPMBT OP firing system is the firing support that you get from the friendly units that are close to your position. Whenever you perform an action, if these friendly units spot an enemy unit (that would be consider as a threat) then they will shot at this enemy unit. Again, if you wish to have direct control over the target acquisition of all your units you should set (to all of them) a very small reaction range in order to avoid this kind of supportive fire.

I think I'm slightly off-topic here, but this seems to be linked to an annoying problem I have often had in urban areas.
I more than once had one unit cornering an enemy squad at a street corner, blazing at them, seeing them perfectly (and I player saw them too), and when I sent another unit to back up the first, even though the enemy was well cleared out, they (the enemy) got the first shots at my second unit who ran off in panic!

Isn't there supposed to be some kind of comm between units, even if relayed by the HQ (myself)?

Or is this some radio issue, or as t been corrected since?

Thanks for any answer
