Colonel
That's like saying if he doesn't have a sword or lance than he is not an infantrymen. With modern all aspect dog fighting missiles, even close in maneuvering dog fighting will really be conducted far outside the envelope of any gun.
All the gun would do is to give the pilot a false sense of hope that he could conceivably not lose and die if he doesn't win the missile fight. It's sort of like giving a modern infantryman a pike..
It has been proven in real combat many many many times that a gun is absolutely essential for a fighter. This is not a question of perception, but a fact proven in actual combats and by actual combat pilots. It's like modern soldiers are also issued knives and taught how to fight with knives although the primary weapon has been projectile weapons for a long long time.
