Hi Commie,
don´t worry, I understand you. You and everyone else are welcome to bring some research or ask for proof regarding anything we do.
I have a good set of data (including photos) of the MiG-23 use during the Afghan war. There´re indeed some MLA being used there, but the images are from weird angles, that doesn´t allow to see the racks or SPO anntenas. But, there´re at leats three UB variants that clearly had the CM mounted. So in this case, I do not expect a mixed esquadron with CM on MLDs and UBs and not on MLAs. That´s somehow a logical supposition.
Second, I´m in the process of confirming if some MLAs were indeed updated with the avionics.
