In 2567 Insurrectionist forces mounted a massive offensive against the United Nations Space Command (UNSC) Misriah Armory on Mars. The UNSC, undermanned due to high casualties during the Human-Covenant war, could defend the armory and in a matter of hours it fell into the hands of the Insurrection. The battle for Misriah dealt a huge blow to Unified Earth Government (UEG) forces and marked a resurgence of Insurrectionist forces throughout the inner colonies and on Earth it-self.
Soon large Insurrectionist cells began attacking UEG controlled buildings and UNSC troops using a combination of suicide bombers, Improvised Explosive Devices (IEDs), and Vehicle Born IEDs (VBIEDs). In retaliation the UNSC, unable to put together a large scale occupational force, began using squads of Orbital Drop Shock Troops (ODST) to occupy cities that were not under UEG control. These ODST troops were tasked with rooting out Insurrection members and uncovering IED production facilities. However, having fought the covenant for so many years, the ODST were ill prepared to combat an enemy that mixed in with the general populace and wore no uniform.
After much deliberation UNSC Central Command (CENTCOM) opted to use psychological warfare against the Insurrection. Snatch and grab operations were authorized against known Insurrection cell leaders and supporters. Those captured were publicly executed or tortured. CENTCOM hoped this brutal display would send a message to the Insurrection. None of you are safe. We will find you. We will eliminate you. We will take any measures necessary regardless of the cost. CENTCOM also put a bargaining chip into play for any members of the Insurrection that were having doubts about their leadership. This plan offered little-to-no punishment for turning one-self in and pledging allegiance to the UEG. The few that turned them-selves in were tortured and executed.
In the summer of 2569 an anonymous civilian from Old Mombasa offered information on a large scale IED production operation in the area of Liberty Street. The day of the meeting his body was found, beaten and decapitated, outside of the NMPD HQ. On the wall behind the man's body the words "Those who support the tyrants will be punished, revolution is at hand," were written in blood. The threat of mass revolution forced CENTCOM to relocate elements of 105th Shock Troops Division, 7th Battalion into the city of Mombasa. One of these elements was the men of Echo Company, 2nd Platoon, 3rd Squad. Call-sign Oracle 3. This is their story.
