*The difference between the Tank, described earlier, and the Grenade, is that the Tank uses focused fire in a single direction, and the Grenade produces an out-of-control explosion in 360 degrees. The Tank takes aim with specific charges, but leaves other useful people and office equipment standing. The Grenade introduces elements that have little or nothing to do with the present circumstances. A Tank attack is a demand for action. A Grenade explosion is a demand for attention.
