Halo: Fleet Battles Campaign Background

Halo: Fleet Battles from Spartan Games is currently holding my entire hobby attention, as I'm a fan of both miniature starship games and the Halo universe. The campaign that comes with the starter box focuses on the titanic (and ruinous) Battle of Reach near the end of the Human-Covenant War, when humanity was digging in for it's last stand. I want to set a campaign at a different time and a different place in the Halo timeline, 5 years before Reach, when UNSC fleets and territory would be larger and allow for a little leeway in what forces are where and when. I've tried to adhere to the Halo lore when creating this background as much as possible, however Wing Commander fans may notice a few nods to that series.

     FLEETCOM Sector Four is one of the sectors making up the Outer Colonies territories. It is known as a former hotbed of Insurrectionist activity among the Outer Colonies, being well-associated with the Eridanus uprising and subsequent Operation: TREBUCHET. However, by 2547, the Covenant's inexorable march had devoured more than half of the sector. While technically on the frontlines of the war, the entire sector has become something of a backwater since Jericho VII was glassed. The Covenant began to shift it's forces away from the area, having found more and more of the densely populated and defended worlds of the Inner Colonies, making Sector Four a peripheral zone of engagement.
    Containing some of the furthest human territories even before the Covenant began it's genocide, the peoples of the region have long been a rugged and independent sort, well-inclined to support the Insurrection. The coming of the Covenant and the subsequent loss of more than half the sector has markedly improved the attitude of the local populaces to the UNSC, if only grudgingly so.
    The sector itself, despite it's reduced size, still holds a wide variation of different planets contributing to the UNSC.    
    Many mining concerns, both legitimate and not, work the vast asteroid fields to be found in the area. Equally large numbers of refineries handle the ore and purify them into the raw materials being devoured by the war effort.
    The Burgundy colony is home to a thriving agricultural industry, and is considered the breadbasket of the sector. A garden world, it also attracts a substantial number of tourists with the means to travel there, in turn creating a substantial tourist industry that makes the planet a favored R&R locale for UNSC personnel of all branches.
    The Sherwood and Pyrenees colonies boast some of the last heavy industry to be found in the Outer Colonies. Sherwood boasts a modest aerospace industry in it's capital city of Loxley, including but not limited to the Broadsword and Longsword fighters, and also possesses several smaller factories dedicated to the assembly of capital-class missiles. While Pyrenees has several large foundries across it's mountainous surface used in the fabrication of heavy construction equipment in addition to a number of large UNSC depot facilities. In orbit, the Hephaestus complex is capable of refining warship-grade Titanium-A plating.
    New Constantinople is a crossroads system lying along several of the established Slipspace routes through the region, and boasts the highest population of any remaining Fourth Sector colony with representatives from every major industry in the sector. A substantial civilian shipyard is present in the system, and SinoViet Heavy Industries has a modest yard turning out Paris-class frigate hulls; coincidentally the only military shipbuilding left in the sector. It is one of the few systems to have a major UNSC presence on permanent station.
    The Delta Prime colony has some of the largest Forerunner ruins in the sector. Consequently, an ONI operation of unknown size is known to be present in the system. SECCOM at Port Zanzibar has no authority over this operation, and it is currently unknown what it's purpose is. ONI is believed to be monitoring all ships present in the system, and civilian vessels deviating from set spacelanes around the colony are always immediately challenged.
    Port Zanzibar is a large space station located in the New Caledonia system. Originally created as a waystation for colony ships traveling towards distant stars, it was largely repurposed by the UNSC into a military dock during Operation:TREBUCHET. A large command complex, additional Titanium-A plating, and numerous Onager MACs, missile bays, and point defense cannons were added to the station to fortify it against expected Insurrectionist aggression. Now, the large cargo bays once used to resupply colony ships hold all manner of consumables used by the UNSC's sector fleet. The command and communications facilities have been expanded to make Port Zanzibar the SECCOM HQ for the region. The docks can accommodate an entire battlegroup simultaneously for resupply, complete with a dedicated AI to coordinate the work, while modest repair facilities can service most classes of UNSC vessels. A habitat block allows the workers and crew to live on-station comfortably 365-days a year.
