Actually it's not that unique...as someone already pointed out, it's similar to USAF 867th attack squadron's patch.
Patch 1
Patch 2
There have been aggressive ancient warriors throughout many periods and many regions...including ours. So there is plenty to pick from that relates more to Pakistanis/Muslims
Adopting/following/mimicking others isn't the way to show enlightenment. USAF, the best in the world, has its own traditions...it doesn't follow other countries...does it make them less enlightened?
I highly doubt Pak would be getting the Greek F16s. Greece just barely got bailed out by EU not too long ago. Their economy isn't doing so well right now. They are not in a position to make new purchases of fighter jets...which means they have to stick to what they got(mainly F16s) if they wanna defend their skies.
Personally I'm not super against this...afterall it is just a name/symbol...and I'm not the type who considers one thing superior to others or looks down at other cultures. It's just that we should take as much pride in our culture as others take in theirs...rather than abandoning our culture while trying to mimick others. So while this single instance in itself isn't a big deal...it is the broader mindset that needs a change.
