Motivating Raiders: Part 1 - Fear

I got feedback from a few people that they enjoyed my Fear, Love, Respect post but missed a part about practical application. The following sequels will attempt to remedy that by detailing ways in which you can achieve each of the three and what consequences that may have. I originally meant for it to be only one sequel but well, it got somewhat big, so we are only dealing with fear today. Love and respect will follow.
If you haven't read the post I linked above, please do that or wait for the other parts of this series before you imply that I suggest ruling by fear alone - I don't.
