United Rebel Front

The United Rebel Front is a complex, well organized faction of Humans devoted to complete liberation from the influence of the United Earth Government and the United Nations Space Command. It is led by three Generals, one of which was General Howard Graves before his death in 2531.

History
The United Rebel Front were a major Insurrectionist organization operating in the 111 Tauri System and other star systems during 2531 at the latest. The Victoria branch of the URF contacted the regional UNSC CENTCOM in 2531 and claimed to have a number of people suffering from Boren's Syndrome, and that they were willing to trade some of their Nuclear Weapons in return for treatment for their people from UNSC doctors. The UNSC sent in five Spartans, known as Blue Team, to take the weapons and kill any rebel leaders. It turned out that the entire plan was an elaborate trap engineered by Graves to capture the Spartans and study them. The Rebels were unsuccessful in capturing the Spartans thanks to Spartan-051 who ambushed and killed numerous rebels including General Howard Graves, with an Asteroidea Anti-Personnel Mine while Graves was "interrogating" the rest of the Spartans, who were unable to move due to the effect of Neural Inhibitor Collars.

Resources
The United Rebel Front had a highly organized intelligence division, and a far flung network of facilities, comprised of a network of different rebel movements, such as the Eridanus Rebels. They commanded facilities such as Eridanus Secundus, Camp New Hope on planet Victoria and Station Jefferson, which was located in the asteroid belt of Eridanus. They also had a high explosives manufacturing facility, operations of an unknown kind on Micronesia, and a saboteur cell on Reach. All these operations were shut down by the Spartans of Blue Team.

The Rebels had an impressive security system, even by Spartan standards: motion and seismic sensors, a triple layering of guards, trained dogs and overhead MAKO Drones.

They also had a number of arms, ranging from military grade MAKO Drones and FENRIS Nuclear Warheads to Archer Missiles and .30 cal "Confetti Maker" machine guns. They used Parabola-class Freighters such as the Laden, to ferry and ship diverse equipment, resources, and weapons from planet systems to their base. They also somehow managed to acquire the destroyer, Origami. They also possessed some "old technology that never panned out" when they used an Antigravity Plate to fool the Spartan's armor systems into thinking they were in a 10 G environment, temporarily giving them decompression sickness, otherwise known as "the bends."

Two Laden-class Freighters were used by the Eridanus Rebels as part of their improvised fleet. They towed the damaged hybrid vessel Ascendant Justice/Gettysburg back to Eridanus Secundus.

Trivia

 * The United Rebel Front made their own version of the standard Warthog, the M12 Warthog APC.
 * It has been theorized that the URF is what became of the remnants of the Insurrectionist movement during the Human-Covenant War.
 * It has also been theorized that the Rebel bases in Halo Wars belong to the United Rebel Front, as they are on maps that take place on Human-controlled planets like Harvest and Arcadia, or others, such as the planet Fort Deen takes place on.
