The Chinese Wu forces were firing off gunpowder-fueled rocket artillery as early as the siege of Yuzhang in 904 AD, although these were more colorful than deadly (save, perhaps, to their crews). The metal-cylinder ones used by the Tipu Sultan of Mysore in the 1780s and the British Congreve rockets in the 1790s weren’t much better. So it wasn’t until the German Nebelwerfer and Soviet Katyusha models of the Second World War that rocket artillery was anything but a curiosity on the battlefield. It was only after the war that designs in rocket artillery made them a mainstay for NATO and Warsaw Pact armies, poised to devastate Europe when the much-anticipated World War III broke out. The minimum recoil of rockets means that lighter carriages are needed, hence these can be more mobile (in fact, some can fire on the move); and advanced ones employ guidance systems, allowing for better accuracy against moving targets.
