The widespread use of recoilless rifles began in 1945, introducing lightweight anti-tank and infantry support weapons that could be effective at hundreds of meters. These innovative firearms allowed soldiers to engage armored targets without the heavy recoil associated with traditional artillery. The adoption of recoilless rifles changed battlefield tactics and contributed to the evolution of modern warfare, enhancing the effectiveness of infantry units.

The widespread use of recoilless rifles post-1945 influenced infantry-focused poetry that addressed the realities of World War II and its aftermath. Poets like Randall Jarrell captured the experiences of soldiers, exploring themes of trauma and the human cost of modern warfare.
