"Therefore, chest-thumping, p*ssing contests and finger pointing at each other is stupid and pointless." Pig Latin Bill, you're about as welcome on this military thread as a pissant at a picnic.
Until you get some bragging rights of your own, don't try to denigrate ours.
It's really none of your business.
If you want to BRAG, go to it. If you want to defend those who slam other branches of the service, then you are the adolescent I suspect you are.
