The 88th Expeditionary Company was a Systems Alliance Marine Corps combat unit attached to the 23rd Expeditionary Battalion and commanded by Captain Kahleigh Waters. The unit was trained at the Recruit Training Depot at Macapá, Brazil in the South American Union on Earth, where it was then stationed in Scott on Terra Nova. Not seeing any action during the Skyllian Blitz or Eden Prime War, the 88th would be redeployed to Colony Grandeur on Horizon as part of the Alliance Colonial Defense Program, helping with the installation of a GARDIAN network to defend the colony from Collector attack and to help recruit and train the Horizon Colonial Guard to defend the planet, giving them Alliance-grade training: at this stage, the unit was under the command of Kahleigh Waters. Unfortunately, the unit was immobilized during a Collector attack in August 2185 CE, with half of the unit being captured and abducted prior to Cerberus' intervention stopping the Collectors from abducting the rest of the colony, and saving half of the unit, with Kahleigh included. In acknowledgement of any potential trauma suffered from the incident, the 88th was pulled out and placed on leave, with the 6th Expeditionary Company deployed to Horizon to take over training of the Colonial Guard and installation of the GARDIAN. After a month of leave, the unit returned to active duty where it was redeployed back to Terra Nova.

The 88th was returned to full strength by the time of the Reaper War, where it assisted Alliance forces in evacuating the colonies before the Reapers attacked the colony. After the evacuation, the 88th would be redeployed across multiple theaters of the conflict, mostly in Operation Hornet's Nest: when the UGC launched its full-scale offensive to finish off Cerberus, the 88th was one of three Alliance combat units deployed to capture Minuteman Station where it lost a dozen men. During Operation Stormwind, the 88th was deployed into London in the vanguard of the Hammer ground forces, where it was mostly wiped out before it could reach a friendly firebase. What remained of the unit was absorbed into the 81st Expeditionary Company prior to the final assault on the Beam.
