Combat credos 
Bader attributed his success to the belief in the three basic rules, shared by the German ace-of-aces Erich Hartmann:
- If you had the height, you controlled the battle.
- If you came out of the sun, the enemy could not see you.
- If you held your fire until you were very close, you seldom missed.
Quote; "Don't listen to anyone who tells you that you can't do this or that. That's nonsense. Make up your mind, you'll never use crutches or a stick, then have a go at everything. Go to school, join in all the games you can. Go anywhere you want to. But never, never let them persuade you that things are too difficult or impossible."
Quote; "Rules are for the guidance of wise men and the obedience of fools."
Quote; "I am not one of those who see war as a cricket match where you first give anything to defeat the opponent and then shake hands."

- Lucas 1981, p. 95.
- Brickhill 1954, p. 44. Note: (also quoted as "...for the obedience of fools and the guidance of wise men.") In Reach for the Sky, this quote is attributed to Harry Day, the Royal Flying Corps First World War fighter ace.
