Thermal Ops

"'Thermal, albeit thanks to our previous Captain's negligence, is sitting on a strategic goldmine. I know Thermal, they're willing to stay put a little longer if it means ensuring the Covies don't get requiem.' -Spartan Commander Palmer referencing the strategic advantage of Fireteam Thermal's situation to Captain Lasky aboard Infinity during the Second Battle of Requiem."Thermal Ops, or Thermal Operations are a sub-set of UNSC operations taking place on Requiem during the Second Battle of Requiem. After being abandoned on Requiem when the Infinity first arrived in July of 2557. Surviving on their own for nearly eight months Fireteam Thermal had secured themselves within a forerunner structure known as Command Site Citadel.

With the return of UNSC forces Thermal was recovered and it was determined they remain at Citadel and lead the Spartan forces in the area, far from the center of conflict the Infinity was conducting. The UNSC Call to Valor, a Charon-class light frigate, was also stationed over Citadel to resupply and defend the secondary landing site of UNSC forces on Requiem. The operations there after were referred to as Thermal Operations or Thermal Ops and were spear headed on the Spartan front by Thermal's leader Spartan Chandler. Meanwhile naval and marine direction was provided by the Valor's captain, Commander Larose.
