Precision-guided munition 精确制导武器
（重定向自Guided Weapon）
- "Smart Weapon" redirects here. For the weapon systems customized to a single person, see personalized gun.
A precision-guided munition (PGM, smart weapon, smart munition, smart bomb) is a guided munition intended to precisely hit a specific target, and to minimize collateral damage.
Because the damage effects of explosive weapons decrease with distance due to an inverse cube law, even modest improvements in accuracy (hence reduction in miss distance) enable a target to be attacked with fewer or smaller bombs. Thus, even if some guided bombs miss, fewer air crews are put at risk and the harm to civilians and the amount of collateral damage may be reduced.
