No, that's not how it is. But then again, how would you want your average fighter/attack pilot to behave? Tea and crumpets with white gloves?
A certain degree of bravado or desire to be the best may be a prerequisite. However, the values most closesly associated with the 18 community are professionalism in everything you do, a commitment to the mission, and comraderie with your squadronmates. From the little experience I have, the hot dogs, jerks, or smug asses don't get very far without being corrected.
Let us put it this way. You show up to your fleet squadron with 26 traps and about 300 hours of military flight training. Your XO, CO, and department heads will have about 10 times those numbers, be technical experts on multiple radars, missiles, bombs, threats, and tactics, be able to take the jet apart with a screwdriver and tell you the names of each wire, and kick your ass in BFM without using afterburner. They will have been to Top Gun. They will have combat experience. They will have balanced a family life with a spotless military career for 10-20 years. Many will have advanced degrees. If a FNG shows up with any of the attitudes you listed, he will be put in his place or he will not make it.
Nobody cares about the cocky asshole with 200 hours in a Cessna who really wants to fly jets.
