Um, the Saudis don’t fly F-16s
They have F-15s, Eurofighter Typhoons, Panavia Tornado IDSes and (I think) still some Panavia Tornado ADVs. But no F-16s
When I was there fifteen years ago they were still flying some F-5s.
They are flying Iraqi f-16’s until their pilots are trained on them if I am not mistaken?
