Thirty years after it was first placed in service, the Jegan remains the standard
mobile suit
of the
Federation Forces.
Though successive upgrades have improved its specifications, the Jegan has been rendered obsolete by the superior performance of the new generation of miniaturized mobile suits. In addition to the standard RGM-89J model, the Federation Forces garrisoned at the
Frontier Side
also employ a high-mobility R type, and an M type armed with batteries of short-range rocket launchers.
