That is quite a fine demonstration of 1v6. Were you actually targetting individual aircraft with all those missiles or just railing off AMRAAMs at the first two suckers in line?
I launched the 6 AIM-120 off in TWS mode. You should be able to see on the RADAR MDI numbers just below each of the RADAR tracks (this is there rank 1's the highest - eights the lowest. Have a read in the Jane's manual 5-113). This function is only reserved for the AIM-120, multiable release of weapons on mulitable targets.
