I think the nitty gritty does matter even in small thing such as discussions on a forum. We already have a tendency to ignore details and the 'chalta hai' mentality has been a detriment for our people and progress. It is thus important to get the details right or at least if unsure, leave them out. This is how misinformation spreads, exponentially gets bigger and once into the mainstream it becomes 'fact'.
On the news itself, it would be great if PAF can get used F-16s. BTW I never believed we had ANY chance of getting any further F-16s from Jordan as they have themselves been buying the MLU birds from Europe. They got rid of their ANG versions of the old non-MLU F-16 and it simplifies their maintenance and training streams too. Possible that there were background deal making for PAF not being able to get additional birds from US directly (perhaps politics or optics). Regardless, RJAF has no spare F-16s to sell PAF so we should forget about that rumor mill.
Now for the European F-16s, their MLU was done up to the M6.5 standard I believe (retired ones that they have been selling are of M5 standard). For those interested to know, there is not one "standard" MLU upgrade. There are multiple versions of the mid-life upgrade that add specific enhancements to the F-16. There was an article recently in AFM that mentioned some of the issues with the Jordanian procurement of Dutch F-16s where the jets were to be downgraded to the M3 standard but there were some hardware/component issues with integration and the US finally allowed those to stay at the M5 standard.
The M3 tape provides Link 16 integration, GPS bombs capability, Helmet mounted sights, NVG compatibility.
The M5 tape further allows for additional stand-off weapons like the dual-mode EGBU-12, Stores management systems, improved GPS and INS systems, newer standard for Link-16 and newer VHF radios etc.
PAF F-16s are at least of M4 standard as it allows for integration of Sniper targeting pods.
