The Dicta Boelcke 

Oswald Boelcke is supposed to be the very first squadron leader in history of aviation. To give his men better instructions about how to behave in battle, Oswald Boelcke created a set of golden rules which are known today as the "Dicta Boelcke". For many years, fighter pilots was flying after these rules, in WW1 as well as in WW2.  And even in our modern times, the jetfighter pilots are still taken these rules into consideration.

1: Try to secure advantages before attacking. If possible keep the sun behind you.

2: Allways carry through an attack when you started it.

3: Fire only at close range and only when your opponent is properly in your sights.

4: Allways keep your eye on your opponent and never let yourself be deceived by ruses.

5: In any form of attack it is essential to assail your opponent from behind.

6: If your opponent dives on you, do not try to evade his onslaught but fly to meet him.

7: When over the enemy's line never forget your own line of retreat.

8: For the Squadron: Attack on principle in groups of four or six. When the fight breaks up into a series of single combats take care that several do not go for one opponent.
