Stop it, you are doing it again !
I will let you into a secret.
If you were an ISIS fighter in a ground position the rounds coming from an F4s gun pod would be just as fast and just as deadly as when the aircraft was brand new!!
The bombs dropped would go bang just as loudly too.
It's worth remembering that when Iran acquired their F4s and F14s direct from the USA they were very much in 'the good lads club' and were buying top notch gear, not cast offs.
