There is decision friction either way. Either you are free to engage without permission as dictated by the rules of engagement on the ground (people are shooting at you) or there is a matrix of agreement that must be met in accordance with law.

The only real economic result attributed to precision is the degree of collateral damage. Is the life of a third world civilian worth the extra expense of more precise technology. As a war fighter I absolutely believe so. Civilian life is simply more valuable than the lives of the belligerents.
