I’ve actually wanted this a couple times myself. But I’ll describe a more specific situation where I would have found it usefull. For an FSO (Friday Night Squad Op) my squad will bring 20 to 24 guys to the table. We will break up into divisions of four aircraft. We’ll all be in a Mission, we’ll all be on one VOX channel – usually a numbered channel not “4-Squad”.
Say, for example, I am a section lead in Able-2, the second four plane division out of a 5 division wing (assuming 20 guys). In this circumstance there are two guys I want to keep track of, that I want to be able to pick out quickly, and they are 1) my division lead, so I can get back into formation quickly. 2) my wingman so I know where he is at all times. Up to now I have to pick one or the other. It would be nice to turn both of them white (My wingman color) so I can spot them quickly.
Another time I would like more than one wingman highlighted is when I am the division lead. I would like to have the three other guys in my flight highlighted white, so they stand out against the crowd of yellow squaddies, it would go a long way to increasing my SA.
In both these circumstances it’s not convenient to tune these guys to a different channel, as that would decrease the overall squad communication.
