The Zulu warriors used a long version of the assegai javelin as their primary weapon. The Zulu legendary leader Shaka initiated military reforms in which a short stabbing spear, with a long, swordlike spearhead named iklwa had become the Zulu warrior’s main weapon and was used as a mêlée weapon. The assegai was not discarded, but was used for an initial missile assault. With the larger shields, introduced by Shaka to the Zulu army, the short spears used as stabbing swords and the opening phase of javelin attack the Zulu regiments were quite similar to the Roman legion with its Scutum, Gladius and Pilum tactical combination.
