By the late 1990s, manufacturers were producing labors for both civilian and military use. Based on the prototype ALX-99 Helldiver Prototype, Shinohara Heavy Industries’ production model ARL-99 Helldiver was designed for airborne drop operations. The Helldiver used the same chassis as the AV-98 Ingram, but was lightly armored due to its role as a paratrooper unit. The Helldiver could equip a variety of weapons for combat, including an arm-mounted 40mm machine gun, an anti-tank missile launcher and smoke dischargers. In 1999, a JSDF Helldiver unit was deployed to a remote forest to eliminate a prototype HAL X-10 military labor that went berserk during testing. The berserk labor was found to be unmanned, and its rampage was the first in a series of incidents where Shinohara’s new hyper operating system caused labors to go berserk under certain conditions.
