Keep the list, and God lists the blessings:
7 And ye shall chase your enemies, and they shall fall before you by the sword. 8 And five of you shall chase an hundred, and an hundred of you shall put ten thousand to flight: and your enemies shall fall before you by the sword.
14 But if ye will not hearken unto me, and will not do all these commandments;
It's a long and ugly list. Best you read it. Considering Israel's history in battle, best that they remain faithful.
