Built by Johnson Industries, the JI-50 or commonly known by its nickname "Jifty" was a commonplace design in the Federated Suns during the late thirty-first century.[2]

The Jifty was used to bring repair capacities to broken and downed units in the field.[2]

The vehicle was primarily produced on New Syrtis at Johnson's auxiliary manufacturing wings. Though by 3069 the Johnson Industries have given permits to smaller companies to manufacture them.[2]

The various invasions during the early parts of the Jihad, had numbers of the Jifty fall into other factions' hands. This happened principally during the Taurian invasion 3067 and House Liao's Operation Thunderstrike has spread the vehicle into the hands of neighboring factions.[2]

Equipment and Capabilities[edit]

The vehicle is equipped with a pair of lift hoists able to handle cargo or salvage. The vehicle has a crew of 6 with 2 serving as gunners for the Jifty's two light machine guns.[2]


The Jifty is equipped with a cargo bay with 19.5 ton capacity with an accessible door in the rear.[2]
