According to my Chilean book about these F-16s were M2s, in Chile they were upgraded to M4, at least the ones that were sold to Chile.
Here is the list of those that were sold to Chile, those that are M4 were modernized in Chile, others were kept at M2:
FACh F-16AM MLU M4 for war thunder
Oh, I forgot Dutch F-16AM it should be M5 Tap for france tech tree in the future
I believe both Belgium Jets (AKA Waffle Nation), both the Block 15 and Block 15 MLU carried the BOL pods but in the prospect where both jets had the capability to also carry either AIM-120’s and/or AIM-9’s on the 2nd inner pylons with the countermeasure pods (I believe its pylons 3 and 8). So curious when Gaijin will give both French/Belgian F-16A’s the capability to carry BOL’s with their missiles instead of having to sacrifice a missile for a BOL pod, which you shouldn’t, most of the ground ordinance is already attached to the CM BOL pods, and since they did IRL, I would give both the A and AM the capability to carry the missiles and pods together, and again, without having to sacrifice either or in the next in game mechanism update or so.
