Battle Factory Season 1 Episode 8 A Grenade Launcher, a Flight Simulator, and Ration Packs

In World War 1, the original grenade launchers were the infantrymen themselves. They both lit and lobbed the mini bombs from the trenches. They could throw the grenade 15 metres fairly accurately, but then would have to duck for cover to avoid the shrapnel from the explosion. Today's version, made in Illinois, USA, has both range and precision.
