One of the many tube launched multiple rocket launchers developed late in World War II was the T34 Calliope. The musical instrument calliope looked a lot like the weapon and hence the name. This configuration was almost always used on a Sherman M4A3 tank. It fired 60 107mm and was used in the Normandy landings. The Russians had the Katyushas. The German had the Nebelwerfer. We had the Calliope.
