a prepared warrior should have no fear. the only fear I would have is of God, that He is who He says He is and that He is a rewarder of those who diligently seek Him. we need to trust God fully so that we can face any devil with confidence that God is on our side as His children. the question Jesus left His disciples with is " when I return, will I find faith?" God knows I want to be on His side!!
I think that a warrior only has one fear, letting others down. I do not think that they care about personal safety or anything like that, but just for the safety of the others.
Different warriors may each have different fears. But, one characteristic that defines the warrior is that they don't allow their fears to control them. They choose to overcome and control their fears. The Christian warrior gives their fears to God and carries on with the mission.
