Qualities of a Spiritual Warrior

Available for battle even in the face of danger
                             Read how God selected Gideon's soldiers 

It is too big, God says. So Gideon asks the fearful to leave (they were not available) 

Anticipate battle even during a time of ease
...but it is still too big. So they go to a brook to drink, and those who drink with their hands are asked to leave, but those who lap the water like dogs can stay (these were ready for battle).
This shrinks the army to 300, less than 1% of the original
Armed for battle with weapons of the Lord's choice
Trumpets (power of praise) and clay pots (smash the pots and the power of God is released)
