In October 2559, Fireteam Intrepid, presumably including "Intrepid One", was deployed alongside Fireteam Taurus, assigned to aid Commander Sarah Palmer in securing nuclear weapons in possession of the Viery Militia toward the end of the Battle of New Mohács.
On December 12, 2559, Fireteam Intrepid was onboard UNSC Infinity when it was ambushed by Banished forces upon arrival at Installation 07. As the Infinity fell to the Banished assault, Captain Thomas Lasky was evacuated from the ship, and Spartan Hudson Griffin ordered all Spartans to evacuate. Fireteam Intrepid left the ship on drop pods, and landed in a sector of the ring occupied by the Banished. The Spartans entered battle upon landfall.
On the next day, Fireteam Intrepid was in a skirmish against the Banished when an explosion on the ring caused a fracture on its surface. Amidst the chaos, Tomas Horvath was separated from the rest of Intrepid. While the status of "Intrepid One" remains uncertain, Horvath remained active as of May 26, 2560.
