Developed by the Earth branch of Zeon Armed Forces, Efreet was a high-performance close-quarters ground combat MS which surpassed the MS-07B Gouf. However, Efreet had an incredibly short production run with only eight units being built during the One Year War before production would be halted in favor of newer designs like the MS-09B Dom.
The Efreet was equipped with a powerful shotgun for mid-range and close-range combat and a pair of heat swords for melee combat. The weapon load-out made the Efreet well suited for close combat. The Efreet also had four smoke dischargers on its frame, which could cover an area in a thick cloud of smoke. This allows the Efreet to move in swiftly, destroy its intended targets, and move out before the smoke clears.
Much like the Gouf, the Efreet was a high-performance close combat ground mobile suit created by the Zeon Earth Attack Force. However, the Efreet had an incredibly short production run. In the end only eight Efreets would be built during the One Year War before production would be halted in favor of newer and more revolutionary designs like the Dom. All eight Efreets was sent to Odessa where they would be tested for further development.
One of the few Efreet mobile suits produced was piloted by Captain Henry Boone, leader of the Zeon's Wolf Gar Team who lead Operation Desert Dragon to overtake the Albatross Transport Base in the Gobi Desert. Another Efreet unit (known as unit no. 5) was piloted by Captain Doug Schneid of Zeon's Marchosias regiment. Schneid's Efreet unit was painted in his custom purple colors, and was equipped with enhanced/experimental armaments.
Other known Efreet units include MS-08TX［EXAM］Efreet Custom, a highly customized conversion piloted by Zeon ace pilot Major Nimbus Schterzen as featured in Mobile Suit Gundam Side Story: The Blue Destiny. In Mobile Suit Gundam: Battlefield Record U.C. 0081, another heavily modified Efreet unit, the MS-08TX/N Efreet Nacht, was seen piloted by Captain Erik Blanke, a member of the Invisible Knights. In addition, Schneid's customized Efreet unit would survive the One Year War and fell into the possession of the Zeon Remnants, who would modify it over years and name the unit after its former pilot turning into the MS-08TX/S Efreet Schneid. The Efreet Schneid would be piloted by Fred Reber during the large scale attack on the Earth Federation's Torrington Base in U.C. 0096.
