While rifle-launched grenades date back hundreds of years, they first came into widespread use during World War One, on all sides of the conflict. The first years of the war saw the use of rod grenades, but their downsides (mediocre accuracy, bulkiness, and a propensity to damage rifle bores) led to the British adopting a 2.5” cup grenade discharger in late 1917. This new launcher used slightly modified Mills bomb hand grenades, and could launch them with significant accuracy from 80 to 200 yards. They would become a staple of WWI combined arms infantry tactics, and be used clear through WW2 until replaced by the 22mm NATO style spigot grenades.

At Forgotten Weapons I think the most interesting guns out there are the most obscure ones. I try to search out experimental and prototype weapons and show you how they work, in addition to more conventional guns that you may not have heard of before. You’re much more likely to find a video on the Cei Rigotti or Webley-Fosbery here than an AR or Glock. So, do you want to learn about something new today? Then stick around!
