The United Rebel Front, also known by the acronym URF, was the overarching organization in charge of many of the activities during both the Colonial Independence Campaigns, and the Human-Covenant War. 
Formed in 2501 by the Insurrection's four main leaders, the URF quickly grew to be the predominant rebel group, with many of the Insurrection's cells coming under the purview of the organization. However, despite having a great amount of strength during the Insurrection, the URF's power began to wane as the Human-Covenant War erupted, and many of its cells either stopped operations entirely or were destroyed by the Covenant.
By the 2550s, the URF was little more than a name, and with the death of its last two leaders in 2552, it fell apart completely, however, some constituent cells still banded together under the moniker.
==History==
===Formation===
The United Rebel Front was formed during a meeting between four of the Insurrection's most powerful leaders in 2501: Generals Adam Makosky and , Colonel , who at the time was also acting as a mole in the UNSC, and the enigmatic Matthias Gavilán. The purpose of the URF, according to the four, was to make a group powerful enough to combat the UNSC effectively and bring all the existing rebel cells under the control of a centralized leadership.
Although the founders' four rebel cells were the original nucleus of the URF, it quickly grew through the men's influence, bringing many of the major rebel groups throughout the galaxy under its command.
===Colonial Independence Campaigns===
As the Insurrection began to escalate, the URF became the main opponent of the UNSC, being responsible for many of the large actions against the UNSC, including Colonel Watts' revolt in 2513 that brought under the control of the Insurrection, albeit for a short time.
As the Insurrection dragged on, the URF became responsible for more and more of the actions against the UNSC, and became more aggressive and organized in their attacks. Along with this, the URF was also responsible for sparking more rebellions and strengthening those already underway, especially during the late 2510s and early 2520s.
However, in 2525, the URF took a major blow when Colonel Watts was captured by the new SPARTAN-II commandos from . Fearing that the Eridanus cell was compromised completely, the URF cut off all communications with it to contain the damage done.
===Human-Covenant War===
Soon after the capture and execution of Colonel Watts, the Human-Covenant War broke out as well. Although most rebel groups stayed active for a period after the appearance of the Covenant, once intelligence reports were leaked to the rebels of how merciless and superior technologically the Covenant were, many simply halted operations and cut themselves off, hoping to hide from the aliens.
Despite this, some rebel groups, including Graves' unit on , stayed and continued to fight the UNSC. In 2531, Graves too died during a raid on his base of operations by Blue Team, during which he attempted to capture the vaunted SPARTANs. The URF's last major action during the war was in 2537, when they succeeded in sparking a rebellion on , both of which were quickly put down by the UNSC. For the rest of the war from that point on, the URF's only actions were scattered skirmishes, raids, and bombings by their very few remaining member groups.
===Dissolution===
In 2552, the last two leaders of the URF, General Adam Makosky, and Matthias Gavilán, were both assassinated by the UNSC. Without their leadership, the URF was no longer able to continue operations, and disbanded into what few member cells remained active.
