Personal ordnance gets the full treatment in this history of the grenade launcher, tracing its evolution from early hand-thrown and rifle-mounted grenades through the development of dedicated launchers like the M79 and the underbarrel M203 attachment. The film moves through the weapon's combat debut and refinement across twentieth-century conflicts, explaining the tactical problem it was built to solve: giving infantry a way to hit targets beyond throwing range but short of mortar fire. Archival photographs and combat footage illustrate each generation of design, while the narration walks through the mechanical changes that made the launchers lighter, more accurate, and easier to integrate into a rifle squad's standard kit. Expert commentary and period material fill in how doctrine and battlefield feedback shaped each redesign. Later sections cover more recent multi-shot and semi-automatic launchers adopted by modern armed forces. It is a focused piece of military hardware history, part of the War Machines series, aimed at viewers interested in how a simple idea, throwing an explosive further and more accurately, kept getting reinvented.
