precision-guided munitions (PGMs)

With the technological development of precision-guided munitions
(PGMs), stealth technology, and satellite-aided navigation, aerial
bombardment has become more precise than ever before. A US stealth
fighter with a single, laser-guided bomb, for example, can now destroy
a target that in WWII required 4500 B-17 sorties dropping 9000 bombs.1
While this increased precision is a welcome development for air
campaign planners wishing to apply the military principle of 'economy
of force,' it has the added benefit of simplifying compliance with
legal and ethical requirements to minimize "collateral damage," or the
unintended bombing of non-combatants and non-military facilities.
