The 28th Fighter Squadron was a UNSC Air Force unit based on the colony of Far Isle. Although initially, the colony was entirely under the control of the Colonial Military Administration, after a series of pro-independence protests turned violent, and some CMA troops and Colonial Militia disobeyed orders and refused to drive the protestors back or joined them outright, the UNSC stationed several units of the UNSC Army and Air Force on the planet. One of these units was the 28th Fighter Squadron, transferred to the planet from Reach. While the next four years still brought trouble to the planet, the local UNSC garrison dealt with protests quickly, and sometimes brutally. While it kept the peace, extremism was on the rise in the pro-independence circle.
