Define the Anglo-Saxon Warrior code and its elements?

I believe the warrior code is called comitatus. It is a bond /warrior code between the lord and his thanes in which the lord provides for his thanes in return for loyalty and protection. The code is based on loyalty/fidelity, generosity, bravery and fate. So, if we examine what Beowulf and the soldiers do (except for the ones that wimp out against the dragon) we can see this code in practice.
