actually there was an exercise of 6 USAF F-15E against one single raptor... raptor toasted all of them.. despite the fact they were flown by highly experienced pilots of rank captain and above
Ukraine and Pakistan has long military ties.. with new US puppet gov in power and with almost regular flights by RAF C-17s picking up small arms, mortars, rocket artillery, ammunition etc from POF.. who knows what else is next.
Besides I wouldn't think much of NATO F-16s operators, sure they are well trained but PAF is on another level. I once met an American whose relative who served in USAF on deputation to Pakistan, in the 1980s he stated
"they (PAF) are better than most NATO airforces"
