Which guided-bomb unit decreases the likelihood of collateral damage?

The GBU-38 is specifically designed to decrease the likelihood of collateral damage due to its precision-guided capabilities. It is a Joint Direct Attack Munition (JDAM) that utilizes GPS guidance to accurately strike targets, which minimizes the risk of unintended damage to nearby structures and civilians. The design and technology inside the GBU-38 allow for smaller warhead options and precise targeting, making it effective for use in environments where civilian presence may be a concern.

In contrast, the other options, while also capable munitions, do not emphasize the same level of precision control as the GBU-38. For instance, the GBU-31 and the GBU-24 are typically larger, heavier bombs designed for different operational effects, and while effective against specific targets, they may carry a higher potential for collateral damage in tightly populated areas. The GBU-54 is a laser-guided bomb that can provide precision targeting but extends reliance on laser designators, which can introduce possibilities of target acquisition risks and limitations, particularly in dynamic combat environments.
