During the Vietnam War, the US military deployed laser-guided bombs extensively from 1972, allowing aircraft to hit individual bridges and fortified targets with far greater accuracy than conventional bombing. This precision-strike capability transformed modern warfare doctrine and reduced (though did not eliminate) civilian collateral damage. The clinical language of precision targeting entered the cultural vocabulary, influencing poets and writers grappling with the moral complexities of technological war.

The introduction of precision-guided munitions in the 20th century marked a significant shift in warfare, inspiring poets like Yusef Komunyakaa to explore themes of remote conflict and the psychological impacts of high-tech warfare in their verses. In works like 'Dien Cai Dau,' Komunyakaa reflects on the disconnection between the soldier's experience and the technological advancements that redefine combat.
