In the military we are always looking for ways to leverage up our forces. Having greater communications and command and control over your forces than your enemy has over his is a force multiplier. Having greater logistics capability than the enemy is a force multiplier. Having better-trained commanders is a force multiplier.

If you believe and have prepared your followers, the followers will believe.
